Sentry Crash Report:

Description Murray Colpman 2010-05-07 23:47:06 UTC 
Application: dolphin (1.4)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-21-generic i686
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
I've been dumping a few of my discs into bin/toc files with cdrdao using the terminal built-in to dolphin, and just occasionally, when the .bin file first gets created dolphin will crash out when trying to read it (presumably) - irritating because I have to start the terminal job again too... the first time it happened, moreover, the bug report window didn't show up, but this time it did.

The crash can be reproduced some of the time.

 -- Backtrace:
Application: Dolphin (dolphin), signal: Aborted
