Is this still reproducible by you? Could you provide a backtrace by gdb attaching to the nautilus process?
An example gdb session like following: (you need type in the part after "$" or "(gdb)" till line ends.) $ pidof nautilus 8677 $ sudo gdb 2>&1 | tee gdb-nautilus.txt (gdb) attach 8677 (gdb) cont Continuing. < reproduce the crash > (gdb) backtrace full Details please see: https://wiki.ubuntu.com/X/Backtracing#Backtrace_with_gdb -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nautilus in Ubuntu. https://bugs.launchpad.net/bugs/879792 Title: the window I had open crashed Status in “nautilus” package in Ubuntu: New Bug description: I had one window with 2 tabs open. I right clicked on a .py file, then selected "open with other application". The dialog box came up, and all it showed was gedit, so I just canceled out of it. Then both the dialog box and the window with 2 tabs both dissappeared ( I assume it was a crash ). And Yes this is a fresh install, only about a couple days ago.
