Comment 2 Philippe Rouquier 2008-06-28 18:54:33 UTC

I committed a possible fix to trunk. I'd appreciate if people could test it.
NOTE: this looks very similar to
#538953 – crash in Brasero Disc Burning: I was trying to copy a C...

Comment 3 Philippe Rouquier 2008-06-29 07:20:39 UTC

This bug seems to be fixed. The reporter for #538953 confirmed the latest changes fix the problem. Feel free to reopen the bug if it isn't.
