[Mono-list] Problem with gecko-sharp and sample applications

[Marcin Zajączkowski]

Hi,


I'm unable to run sample applications for gecko-sharp. It gets SIGSEGV 
(stack trace below - if it needed I probably could add some debug 
symbols for it).
I tried with gecko-sharp-2.0-0.11 (installed on my system from RPM - 
Fedora Core 6) and sample applications from gecko-sharp-2.0-0.11 
tarball. I modified compilation command to have:

[marcinz at bolger sample]$ /usr/bin/mcs -unsafe 
-lib:/usr/lib/firefox-1.5.0.12/ 
-r:/usr/lib/mono/gecko-sharp-2.0/gecko-sharp.dll -lib:/usr/lib 
-pkg:gtk-sharp-2.0 -out:WebThumbnailer.exe ./WebThumbnailer.cs

libgtkembedmoz.so was taken from firefox-1.5.0.12 (and from 
thunderbird-1.5.0.12) (also from RPM). I seems to be linked with gtk2:

[marcinz at bolger gecko-sharp-2.0-0.11]$ ldd 
/usr/lib/firefox-1.5.0.12/libgtkembedmoz.so | grep gtk
        libgtk-x11-2.0.so.0 => /usr/lib/libgtk-x11-2.0.so.0 (0x06b19000)

I tried also with that lib taken from esc (Enterprise Security Client) 
which didn't get SIGSEGV, but I only saw white window.


Could it be problem with libgtkemedmoz.so? I so, where can I download 
its "working" version?


Thanks for help
Marcin

Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
