[gcmd-dev] Clicking the SMB button causes SIGSEGV in libgnomevfs-2.so.0

[Manuel Bua]

Hello, i just checkout the master branch and was eager to try out the new
1.4 and i like it pretty much, thank you for your work!
However, trying to browse Samba shares causes gnome-cmd to segfault, here is
the backtrace (w/ full gdb version info):

I'm using 1.2.8.10 for day-to-day work and this feature obviously works
fine: when testing 1.4 i renamed my previous ".gnome-commander"
configuration store so that i'm sure the problem is not related to
previous/deprecated settings and such.
If you need some more debug information just let me know if there are any
switches i can enable to recompile with more useful dbginfo, i will be happy
to provide them.
