Sentry Crash Report:

Description Jean-D. Ackle 2013-10-25 11:56:44 UTC
Application: k3b (2.0.2)
KDE Platform Version: 4.9.5
Qt Version: 4.8.3
Operating System: Linux 3.5.0-42-generic x86_64
Distribution: DEFT Linux 8

-- Information about the crash:
More system information:
Using DEFT 8 yes, but with the Ubuntu Quantal it is based software sources.
Using the LXDE (I could not really pinpoint the version, each LXDE package has its own...) with Openbox 1.0.1, both the default OS default choices.

- What I was doing when the application crashed:
I was not interacting with K3B at the moment of the crash, nor was it performing any user-started operation. It was minimised and inactive.
I had loaded a previously saved project to it and I had added some additional folders to the project (unsaved).
I had mounted an SD card and I was creating a new folder (using pcmanfm 1.0.1-0ubuntu) and giving it a name.
Both PCManFM and K3B crashed at the same time. (I got no suggestion, from the system, for filing a bug report against pcmanfm).

-- Backtrace:
Application: K3b (k3b), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
