I have added breakpoints to XrmGetFileDatabase, XrmGetStringDatabase,
XrmDestroyDatabase and I found out that XrmGetFileDatabase and
XrmGetStringDatabase are called when mged starts before selecting the new
dm. When the dm is selected there are no occurrences of any of these
function (this happens for all the dm's not just the Qt one) and then when
closing mged XrmDestroyDatabase is called and when using Qt it gets a
segfault so the resource is created then destroyed somewhere else and then
the segfault occurs.

Cheers,
Vlad
