Hmm - just reproduced the crash twice when wanting to do the same correction.
Comment 2 Thomas Friedrichsmeier 2011-05-06 19:06:24 UTC 
> Hmm - just reproduced the crash twice when wanting to do the same correction.

Could you attach the file in question, and tell us, where to insert the new-line? That would probably be very helpful.
Comment 3 Pascal d'Hermilly 2011-05-09 15:35:16 UTC 
unfortunately the file has been changed quite a few times since and I've not experienced the crash since. 
Even if I still had it it is a quite large file with a lot of in-house code that I might have problems with releasing. However I will see if I can reproduce in other ways and give an example file.
Comment 4 Dominik Haumann 2011-05-15 09:55:14 UTC 
It's a known problem, but no solution was provided, yet. Reproducibility would be awesome...
