pgAdmin 1.8.x hangs while tries to load XRC resources

I have a problem in getting pgAdmin3 working since the 1.8.x series.
I usually build pgAdmin from source (however also the binary releases
give me the same problem) and whenever I try to run pgAdmin it shows the
splash screen and then it always hangs. After having traced the exact
point of hanging, I noticed it always hangs at file
pgadmin/ui/xrcDialogs.cpp line 13760 (1.8.4 version) at the point of the
first wxXmlResource::Get()->Load call.
I also tried to disable EMBED_XRC define and to copy all the XRC files
to [uiPath] with no success. I am currently using wxGTK 2.8.7 and all
the other requirements (in particular libxml2, ver. 2.6.32) seem to be
right. By the way: I am using Linux (Fedora 9). No problem if I use
pgAdmin 1.6.3: it complies and runs smoothly and with no problem. I am
having this problem since the release of pgAdmin 1.8.0
Do you have any idea of what the problem can be?

Thank you for your support and help.

Best regards.

Antonello
