Application: konstruktor (0.9.0-beta1)
KDE Platform Version: 4.5.5 (KDE 4.5.5) (Compiled from sources)
Qt Version: 4.6.3
Operating System: Linux 2.6.37 x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
After downloading the LDdraw library from http://www.ldraw.org/library/official/ldconfig.ldr, unzipping it, I started konstruktor and selected the place I unzipped it. After the progress bar finished, the program crashed, as it did on all subsequent attempts to start it again (without showing a file selection dialog or progress bar).

The crash can be reproduced every time.

-- Backtrace:
