Do you happen to have trinity-tdeio-umountwrapper installed?
It cause weeks worth of problems for me until I figured it out.
If you do have it installed, try uninstalling it.
Also look at your inode file associations.

Maybe I'm barking up the wrong tree here but I thought I'd mention it.

Good luck, please let us know what you find.
