Bug Description

1. expected behaviour:

Open folder to view content

2. What happens

Nautilus crashes with dmesg error as below (same folder /home/pasi/Videot/Areena always triggers crash, maybe there is corrupted files but anyhow I do not expect nautilus to crash):

I have noticed that nautilus crash is related to the thumbnailing process that causes nautilus to crash when trying to process 0 lenght .flv file.

Same folder that causes Nautilus to crash can be view by remite machine over SMB, because Nautilus do not show thumbnails by default on remote folders.nn

I got same crash. Found similar errors in syslog:

============================

============================

I was moving files between disks, for more details, I run 'nautilus' from terminal, so I got more information:

============================
sys:1: Warning: GError set over the top of a previous GError or uninitialized memory.
This indicates a bug in someone's code. You must ensure an error is NULL before it's set.
The overwriting error message was: Error removing file: Permission denied
Segmentation fault (core dumped)
============================

So, for me, it because the source file cannot be deleted for permission reason, but anyway, the nautilus shouldn't crash, it should report the permission problem.

Nautilus crashes with any 0 size file

I do not get Nautilus to crash with ANY zero length file like:

1. touch test, touch test.doc, touch.ppt...

2. open directory that contains these zero length test files --> no crash

But if filename (extension) makes file to be media type then crash happens.

3. touch test.flv --> crash

4. touch test.mp4 --> crash

5. touch test.mp3 --> crash

6. touch test.avi --> crash

and so on, the crash is somehow related to media file "preview" generation I think.
