Description (last modified by dbevans (David B. Evans))

I'm migrating an application from GTK2 to GTK3 and while it launches when using XQuartz, it fails when trying to use an X server running on a different machine (Windows using Xming 7.5.010).

The trace is:

Could not modify the original submission for a better formatting of the trace, so here it is:

Owner: changed from macports-tickets@… to devans@…
Port: libepoxy added
Status: new → assigned
Summary: Crash in gtk_init_check → libepoxy: crash in gtk_init_check when calling epoxy_glx_version

This does appear to be an instance of the problem discussed in upstream github issue 72. The implication is that your remote server does not support GLX. But there definitely should be better error handling here. Will review upstream suggestions and see what can be done.
