[Gtkradiant] bug with the face select tool.

[hyp3r focus]

i've recently built gtkradiant on ubuntu 32bit 7.10 and it compiles fine,
but there is a weird bug. if i make a brush and then hit "f" to use the
"select face" tool then gtkr crashes. this also happens when i click the
"select faces" icon./home/john/bin/gtk: line 2:  8816
Aborted                 (core dumped) ./radiant.x86

i've downloaded a fresh copy of the svn code and re-compiled it but the
error is still there, so i'm running out of ideas. i've run gtkr from the
command line and here's the error message it gets when gtkr crashes.....

radiant.x86: vbo/vbo_split_inplace.c:97: flush_vertex: Assertion `max_index
>= min_index' failed.
/home/john/bin/gtk: line 2:  8816 Aborted                 (core dumped)
./radiant.x86

any idea what the problem might be?

thanks for your time.
