Can you explain what this bug report is about? http://www.thewildbeast.co.uk/claws-mail/bugzilla/page.cgi?id=bug-writing.html
Just to be sure: were you unloading plugins while incorporating messages?!
It often happens that claws-mail just disappears. (one or two times a day). Meanwhile i am used to this, as no data loss happens. Shortly I ran claws from the command line with --debug and saw the sent trace. I was in the process to send an encrypted mail (which failed several times before with no clear reason): "Couldn't encrypt the email: Encryption failed, General error Use "Send queued messages" from the main window to retry." So I tried to change pgp plugin from pgpinline to pgpmime. > were you unloading plugins while incorporating messages I think there was a message window open during unloading.
Could you reproduce it with gdb?
sending encrypted messages via pgpinline fails with: ** (claws-mail:24454): WARNING **: sgpgme_data_release_and_get_mem failed

Would you mind to build your Claws Mail with debug info (no stripped binaries) or install your distribution debug symbol packages (if available) ? Your backtraces would be more useful. Trying to reproduce them with latest version (3.9.0) is also appreciated. Thanks in advance.

With gdb, read http://www.claws-mail.org/faq/index.php/Debugging_Claws BTW, these "error reading variable: Unhandled dwarf expression opcode 0x0" errors are a bit scary, be sure your gdb is recent enough to be able to read the debugging info your compiler generates (that's a guess, could be something worse :)
1) load freshly compiled notification plugin (0.31cvs4) > "Your claws is too new" 2) uninstall the plugin (make uninstall) 3) plug off the cable, click through the synchronized folders in offline mode 4) plug in the cable again quite instantly the following segfault happened. You may think, its quite uncommon, that plugin libraries just disappear. However in my eyes claws should not crash.

this is becoming a quite long ticket. I try to sort the errors a bit 1) segfault while writing a message after removing a plugin (#c1) 2) "sgpgme_data_release_and_get_mem failed" with unusable secret key (#c6) 3) segfault related to cmov/libc.so.6 (#c8) 4) segfault "double free or corruption" because of missing plugin file (#c15) 5) malloc.c: No such file or directory. (#c16-18) I know, that this is hard to debug as the conditions are not clear. also this time this segfault happened in the background after cable plugin/off. How to find out, which file is missing? ** (claws-mail:9073): WARNING **: [13:26:34] IMAP error on *.net: stream error ** (claws-mail:9073): WARNING **: [13:26:34] IMAP4 connection broken Program received signal SIGSEGV, Segmentation fault. malloc_consolidate (av=<optimized out>) at malloc.c:5153 5153 malloc.c: No such file or directory.

The first part of the title of this ticket makes no sense. It is because no debugging information is found. The backtraces aren't useful due to the lack of details. The second part of the ticket's title is more relevant, because networking troubles (such as losing the connection or going offline) while Claws Mail is busy working on IMAP, leads to trouble, which causes side-effects and memory corruption somewhere. That's also why glibc memory management runs into those issues and aborts Claws Mail when arbitrary parts of it try to allocate/free memory. ** (claws-mail:545): WARNING **: [20:30:38] IMAP4 connection broken ** (claws-mail:545): WARNING **: [20:31:52] IMAP error on (null): stream error *** glibc detected *** /usr/bin/claws-mail: double free or corruption (!prev):
there's too much noise here. I'll close this, but feel free to create a new bug item which contains the pertinent information
