Bug 204274

- Can you reproduce the crash at will ? Thanks
Merging with bug which has a similar backtrace. Thanks

*** This bug has been marked as a duplicate of bug 193364 ***

It is not easily reproducible since it's happening apparently randomly: Dolphin didn't have the focus and I was working on something else when it simply crashed. However it happened for a second time in two days: the backtrace below seems indeed to be the same as the one in bug 193364.

Same as yesterday, I had two tabs opened: one in a local folder, one on a FTP server.
I don't remember what was the local folder for yesterday crash, but this time I'm quite sure it was a folder containing LaTeX .tex files I'm regularly compiling (although I wasn't compiling at the very moment of the crash), and it was displayed using the columns view.

I got again the same issue (so I'm not copy-pasting the backtrace again) as the very first one I reported here yesterday, but in a different context this time. I still had a session of Dolphin opened with two tabs (no FTP though this time, just two local folders) and I plugged in a USB key. When choosing "Open in Dolphin" from the pop-up window, it crashed the existing instance of Dolphin.

Unfortunately, it is still not reproducible: I tried to plug the very same key in the same port while having reopened the same tabs three times and it worked correctly.
