-- Information about the crash:
kgpg was running for ~30minutes in the background.
Then it crashed without any interaction from my side...
The crash can be reproduced some of the time.

This looks very much like some assertion is hit. Please start KGpg from a terminal session and paste the output that happens shortly before the crash here.
Will do, but the crash happens only very rarely...
There you go!
Qt has caught an exception thrown from an event handler. Throwing
exceptions from an event handler is not supported in Qt. You must
reimplement QApplication::notify() and catch all exceptions there.
terminate called after throwing an instance of 'std::bad_alloc'
KCrash: Application 'kgpg' crashing.
Ok, there is some sort of memleak happening. Could you try running
valgrind --leak-check=full kgpg --nofork
This will likely be rather slow but hopefully gives me a clue what's going on.
Created attachment 65870 [details]
the funky signature
This is not going to work.
I had some time to look a bit closer at the problem.
Kgpg seems to get stuck in an infinite loop by opening the attached pgp-signature.
Within this loop it allocates from time to time some memory, after a few hours it crashes...
You can reproduce the issue as follows:
1. kgpg --nofork
on a second shell:
2. kgpg signature.asc
Now the first kgpg process consumes 100% cpu until it crashes due to std:bad_alloc.
Thanks for the info, now I know what is happening. KGpg tries to decrypt the signature and gots stuck in it's communication with the underlying gpg process.

prevent KGpg to endlessly loop while trying to decrypt a detached signature
This can't work, so there is no value in trying it.
