Bug 353557

Note: Adding new identities work, but not if I ask to duplicate the problematic one.

It appears as «Come» while I might have put «Côme» intially as the identity name, I don’t remember.
Please ask for any other needed information.

I need a real backtrace :)

Stack trace

Grr, the bug tracker lost my comment because I attached a file.
I was saying the bug report tool is saying my stack trace is useless, and it points to https://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports which says using Arch I’d have to build everything from source, which I’d like to avoid.

Perhaps qt5.5.0 has a bug because I can't see a kmail bug here.

I have encountered the same problem (kmail crashes in most attempts) here with a very similar stack trace that ends up crashing in _gpgme_ath_mutex_lock in libgpgme.so.  It might be some rushing conditions there.  Considering that we are in a multi-threaded environment, I tried to run kmail with

LD_PRELOAD=/usr/lib/libgpgme-pthread.so.11 kmail

in Arch Linux and it seems to be solving the problem and all encryption features work fine.  I am not sure libgpgme-pthread is the proper library that kmail shall link to though; even in that case the problem can be in cmake or elsewhere.

Kontact crash log

I'm also experiencing this. I've attached my konsole output, since it may provide any helpful information.

It also crashes if I try to create a new identity by copying that identity.
I'm using KMail 5.0.2
