Bug 127336

Could you please post a backtrace? That way it's more easy to fix this bug.

I'm sorry, Bram. In fact I've saved it locally but just forgot to upload the file.

Konversation's backtrace after crash when making a DCOP call

The backtrace doesn't help because it doesn't contain some debug symbols.
Could you compile Konversation from source with the option "--enable-debug=full" and generate a backtrace with the compiled Konversation?
( ./configure --enable-debug=full )

I'm sorry for the inconvenience.

Another backtrace, this time with full debug symbols and info

Created attachment 16185 [details]
same backtrace but with full debug information
