inkscape strikes again

[Csaba Henk]

Hi!

Browsing the archives, I've seen that inkscape became problematic in
FreeBSD since they rely on Boehm GC.

For me, I can compile it just fine on my 5.4-RELEASE, but the prog can't
start up. Using the port as is, I just got a coredump. Looking at the
backtrace, there were various points where the prog blew up, but in all
cases, it was related to pthread.

So then I disabled pthread support (recompiled boehm-gc using the
appropriate config settings + deleted -lpthread from LDLFAGS of the
CONFIGURE_ENV in the inkscape Makefile).

Now I see things like:

Emergency save activated!
Emergency save completed. Inkscape will close now.
If you can reproduce this crash, please file a bug at www.inkscape.org
with a detailed description of the steps leading to the crash, so we can
fix it.

(:27978): GLib-GObject-WARNING **: cannot retrieve class for invalid
(unclassed) type `(null)'

If I run it in gdb, the following backtrace can be seen after a
segfault:

(gdb) run

Is there any trick/hack/patch which can make it work? Can it be that these failures are specific to my setup? Note that I tried to use the package on another box and it segfaulted there, too.

Couldn't/shouldn't this port be gracefully marked broken for a while?
