I'm using a daily updated dapper, however this is not an originally installed ubuntu, but rather an ex-Debian-sid system.
The string in question is to be found in the gucharmap package, since I don't really need it, I removed it and it indeed fixed the problem with the run app dialog. However, I still have the same problem with gaim, where renaming a buddy to a full name (i.e. with spaces in the name, one word works fine) yields this backtrace:

For obvious reasons, I can't just remove the buddy and be happy. Malone bug #6071 seems to be the same.
