Bug 432039

SUMMARY
krusader crashes with pane opened to a directory to which files are being added by firefox and downthemall extension.


STEPS TO REPRODUCE
1. Open krusader in dual pane mode.
2. Point one window to an empty directory in which files are going to be downloaded.
3. Use Firefox and the Downthemall extension to download a number of pdf files from a website.

OBSERVED RESULT
4. Krusader shows the files being added until krusader crashes.


EXPECTED RESULT
5. The files being added to a directory should not affect krusader, let alone cause it to crash.
