Please tell which command you invoked.  If you happen to know which
function checks the trustdb and hung, that would be even more helpful.
I almost never use epg and am not familiar with its code, and I don't
think we have epg experts on board to ask them to look into this.  So
I need every possible help from you to find the place where such a
message would be useful.

I agree, but I'm not aware of anyone around who knows enough about epg
to produce such an explanation.  The code is quite convoluted and
studying it is not something I can afford, sorry.  Patches are
welcome, of course.
