Bug Description

Binary package hint: pcmanfm

In a Lubuntu Desktop session in a Natty amd64 system with pcmanfm 0.9.8+git-6240436419-0ubuntu1 and libfm0/libfm-gtk0 0.1.15+git-3625952cea-0ubuntu1, I attempted to browse a share in PCManFM which was mounted via smbfs, during a time when the share was temporarily down because Samba packages on the server (also a Natty system) were being upgraded. This crash occurred, probably as a result of the folders I was browsing to being inaccessible. I don't remember which of these two shares I was attempting to access (output from the mount command on the client running PCManFM):

//Del/dAlembertian/ on /media/dAlembertian type cifs (rw,mand)
//Del/Laplacian/ on /media/Laplacian type cifs (rw,mand)

A terminal log documenting the upgrades being installed on the server is attached. Please note that this is from the server (hostname del), while this bug occurred on the client.

To the best of my knowledge, this crash has only happened once. But based on the above information, I believe I could reproduce it deliberately by shutting down the samba daemon on the server. I'd be pleased to do this if it would enable me to gather and provide any other useful information.
