Steps to reproduce: 1. Right-click a message -> "Apply tags", "Add" some new tag to a message 2. Immediately click "Delete" to delete the tag again 3. Tags stays in the list 4. Try to "Delete" the tag once more -> Crash The only way to avoid the crash is to "Close" the dialog after deletion, and then reopening it, the tag is gone.
I see your 3rd point - Tags stay in the list when deleted, but I don't get the crash.
Created attachment 1704 [details] full backtrace Automatically created by ABRT on Fedora 25 x86_64 with Claws Mail 3.14.1 from updates-testing.
Seems to be in libetpan, right?
NULL ptr passed to strlen. 230 int mailimap_token_send(mailstream * fd, const char * atom) 231 { 232 return mailimap_sized_token_send(fd, atom, strlen(atom)); 233 }
That would make sense as I don't use IMAP.
Oh, and libetpan is still at 1.6 here, not 1.7.2 yet.
we are students and we are working on this bug. we resolved the crash and just Removed tags from the display but not on "data base". Where we can find the source tag ?
