-- Information about the crash:
- What I was doing when the application crashed:

Absolutely nothing.  karbon did not have focus and I wasn't actively using it at all!  Maybe triggered by a periodic timer e.g. autosave?

The crash can be reproduced sometimes.

-- Backtrace:
Application: Karbon (karbon), signal: Segmentation fault
