pcmanfm crashed with SIGSEGV in gtk_widget_get_toplevel()

[Kevin Freeman]

Didn't give me much info; just said a program has crashed. I haven't had a lot of luck with any linux distro for my hp pavilion G7, mainly because of display driver issues with pre 3.2 kernels. I have tried other distros with 3.2 or later kernels, however, and still encountered numerous problems. So far, Ubuntu is the only one that works reasonably well, other than giving me these program crash notifications frequently and hanging during boot on occasion.

If this is going to be read by Ubuntu designers, it would be great if Ubuntu had more dialogue windows that popped up to let you know what's going on so you don't just think the computer has frozen when it's just applying updates, etc.
