OpenBSD: Inkscape hangs/segfaults

[Clock3]

I managed to compile inkscape-0.44 on OpenBSD. I had to
replace isNaN calls with isnan, isfinite with finite
and write my own log2 function
return log(x)/log(2)

When I run inkscape, then it doesn't do anything and
consumes 100% CPU (tested for several minutes).

When I run gdb inkscape and run, it segfaults immediately
with the following stack trace:

this is only a guess.
1. if you still have a file $HOME/.inkscape/preferences.xml
from an older installation, wiping that might help.
2. if it does not, what Boehm libgc do you have? downgrading
libgc-6.7 to 6.6 might help too.
3. a third possibility is to try export INKSCAPE_GC=disable.
and
4. in the past, it also was quite successful to use valgrind
instead of gdb (including the above export command) for
finding the exact position of the crash.

sorry to be so unspecific.

Could someone confirm if this is still occurring on BSD?
