[tomboy-list] Crash at startup on Vista

[James Chaldecott]

Hi,

I've recently started getting a crash at startup on Vista SP1. I was
using 14.2 and just upgraded to 15.1 and they both crash as soon as I
run the executable.

I think 14.2 was working fine up until recently. Certainly I had a
14.x version of Tomboy working, and I don't  *think* it stopped
working as soon as I upgraded to 14.2.

The output when running from command-line is as follows:

Debugging in VS2008 let me grab the following exception detail (no
that it's any different from the above!):

System.AccessViolationException was unhandled

Looking through the modules list, all the gtk-sharp dlls (managed &
unmanaged) have loaded from "C:\Program Files\GtkSharp\2.12\" (or the
GAC - still version 2.12), but libpng13.dll & zlib1.dll both loaded
from "C:\Windows\". Is that normal?

The loaded libpng13.dll is showing version 1.02.36.0.
The loaded zlib1.dll is showing as version 1.02.3.2027.

I've checked & notice that there are indeed copies of libpng13.dll &
zlib1.dll in "C:\Program Files\GtkSharp\2.12\bin" which I suppose are
the ones we should be using. It looks like that directory is on my
PATH, but it comes after %SYSTEMROOT% (i.e. "C:\Windows").

I just tried moving "C:\Program Files\GtkSharp\2.12\bin" to the start
of my PATH (and rebooting), but it made no difference. The offending
dlls were still loaded from "C:\Windows".

Any ideas?

Cheers,

James

P.S. I can't stand unmanaged code these days. I was a C++ dev for 5
years or so, and I used to think it was great, but every time I have
to go back into that world from C# I can't believe how horrible it all
is!
