Comment 1 Bram Schoenmakers 2007-12-16 20:45:00 UTC

Could you try rebuilding KDE 4 with debug symbols please? That would make the backtraces more useful.

Invoke cmake like this:

cmake -DCMAKE_INSTALL_PREFIX=$KDEDIR -DCMAKE_BUILD_TYPE=debugfull /path/to/src

Comment 2 Rolf Eike Beer 2007-12-17 00:34:22 UTC

And please give the exact revision number of your checkout.

Comment 3 Oliver Putz 2008-01-28 05:41:58 UTC

I can confirm this bug with kdelibs r766524 and kdeutils r765739. The key generation process crashes at the last step, when I am about to create a revocation certificate and click on "ok". The key however gets correctly created and set up. My backtrace is:

Application: KGpg (kgpg), signal SIGSEGV

I will port this over to KProcess tonight, that should help.

Hi, I just checked with kdeutils r767828 and can confirm that this bug is resolved. So you can backport.
