GTK-Wimp enabled causes ethereal to crash on startup
Also, could the "help" -> "about" box please display the GTK-Wimp
version no. - then we'll be able to tell you which version we're
running :-)
I was wondering how it could be that GTK 1.3 crashes with GTK-Wimp.
GTK-Wimp is an extension for GTK2. GTK1 doesn't even load it!!
So I installed GTK1 version with GTK-Wimp and at least this time, I
can reproduce the crash.
The debugger shows that it crashes when loading asn1.dll.
I am not surprised that we finally have a conflict with it as it is
linked against GTK2!
Once upon a time, GTK2 was used in the plugin. It has been removed
[placed within "#ifdef DISSECTOR_WITH_GUI" conditionals, which are
normally false] as one of the first things done after being accepted
in the ethereal tree. If that was incomplete, I need to correct that.
So do we have to link the asn1 plugin with GTK?
The crash already happens in libglib-2.0-0.dll. I believe that most
people reporting crashes with ethereal crashing in module
libglib-2.0-0.dll have this conflict.
Yes, glib is used extensively, for managing lists, trees, arrays and
printing error messages. This can only be removed by having private
implementations of these routines...
Of course, I don't want to remove glib dependency. And there is probably
no problem with it. It is just a hint to those people reporting a crash
of ethereal-0.10.6 in module libglib-2.0-0.dll that they probably have
an asn1.dll which was linked with GTK2 libraries causing a conflict.
Although it is a conflict between different GTK libraries the crash
occures in GLib.
Or, if I know the real problem, I can change the code to avoid it...
There are a lot of workarounds, but there is only one solution:
Remove GTK depedency from the asn1 plugin.
I think there is no GTK dependency any more,
only a glib [maybe version 2] dependency.
Then we should be able to link the asn1 plugin without GTK.
I will try that. It wasn't possible the last time.

Lars
