Description pvoigt 2012-11-22 15:35:04 CET
When searching in LDAP addressbook Claws crashes. It is not exactly predictable when the crash occurs but after numerous tests I've found out that it happens at least after four searches with arbitrary search names, e.g. some searches previously finish with correct result and no crash.

I'm using an address book stored in an openLDAP server under Linux with mozillaAbPersonAlpha.schema.

The Linux version 3.9.0 (compiled from source) is obviously not affected.

The used Windows version of Claws Mail is http://www.claws-mail.org/win32/claws-mail-3.9.0cvs12-pkg23.exe.

Please find attached the Windows crash report (German Windows version).

Faced the very same issue; in my case I was running Claws version 3.9.1-2-g66aa06 on Windows7 x64, added an LDAP server pointing it to a Linux box running OpenLDAP, address search (tab-autocomplete) worked just fine, but in some cases, usually after entering 3 or more addresses, when tabbing over another partial address claws crashed
Comment 3 Simon Arnaud 2013-06-03 11:18:19 CEST
I have this problem with Windows Seven 32b.
version 3.9.1-2-g66aa06
Querying an active directory domain controller.

It always crashes a few ms after the result of the search for the third contact appears.
It never crashes for the firts and second contact.
It also does not crash if I do not search (Tab) the contact.

The newest package, claws-mail-3.9.1git2-pkg42, has resolved the problem for me so far. We will see in the long run.
Comment 5 Paul 2013-06-14 09:32:47 CEST
Ok, thanks for reporting. Re-open if necessary!
Comment 6 pvoigt 2013-06-14 10:37:45 CEST
I've just re-checked the LDAP search issue with the latest Windows version of Claws Mail:

Unfortunately, the bug still exists in an unchanged manner.

Operating system is Windows 7 Pro x86_64 DE.

Re-opened bug report.
Comment 7 Simon Arnaud 2013-06-19 18:06:57 CEST
I also confirm that the bug still exists, but is not as reproducible as before.

Searching LDAP from address book also crashes.
Comment 8 Marius 2014-09-24 11:16:29 CEST
I can also confirm this:
Claws Mail
version 3.10.1

Windows 7 AMD64

It crashes everytime when I search for the second email address.
