Seeing the debugger log (contents of right pane of Windows -> Views ->
Debugger log) is often helpful in such cases.

My current suspicion is that your compiler is gcc >= 4.6 which seemingly
changed object layout for std::map. There is a patch from March making
the Qt Creator dumpers work with both versions. That was post-2.4, though.

If that's the problem, using a recent version of Qt Creator (2.6 was just
released, but 2.5.x has that fix, too) should work.

If it doesn't, it's a different issue, and I'd really need to see the full
debugger log and the definition of the type you want to display inside
the map (just member variables are ok, I don't need functions etc).
Private mail is ok in that case.

Best regards,
