use of menus crashes Firefox?

Hmmm. OK.

I did this:
$ gdb /usr/local/lib/firefox3/firefox-bin 10388

This results in Firefox being locked and non-responsive to the user
interface. It can't even draw the screen if I switch to that desktop,
there's just a window frame hanging there. Even clicking the close button
(the "X" in the top corner of the window) doesn't do anything... nor
does right-clicking on the window title bar and selecting "close." If I
quit gdb, then firefox becomes responsive again.

But it does put this in the console where I ran GDB (there's a
lot). there are 11 [New Thread x (LWP y)] lines, and one error line. The
error line is right at the end
"0x29e581a7 in __error () from /lib/libthr.so.3"


This GDB was configured as "i386-marcel-freebsd"...(no debugging symbols
