Description Matthew Dawson 2015-01-25 04:12:58 UTC 
-- Information about the crash:
While I was working on my computer, Kelopatra randomly crashed in the background (I wasn't even aware it was running at the time).  I think I may have been looking at some signed emails around that time.

I double checked the generated binary, all the null checks are present.  It did fail copying the fpr member of subkeys, and the register holding the pointer for subkeys had an address of 0x90, which seems weird to me.

I have a core dumped if you have something more you'd like me to poke into, and I can keep the debug symbols/source code around for a couple of days.  I lurk in #kde-devel as MJD, feel free to ping me.

-- Backtrace:
Application: Kleopatra (kleopatra), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
