Hi. I am not a Rosegarden dev, but I am a Gentoo user so I am curious as 
to why you are having problems. I am running Rosegarden 11.11 on an 
amd64 box and never had any trouble starting it.

 From simply the information you gave, the only differences I see 
between my installation and yours is:
- I am not running KDE (or any DE)
- I am using qt 4.7.2. Everything higher than that appears to be masked 
out for amd64 (and for x86)

So, I'm totally guessing (I haven't looked at the Rosegarden source code 
at all), but the first two things I would wonder about:
- Is there some incompatibility issue with the newer versions of QT? A 
quick look at the Changelog the other day indicated that there are a 
massive amount of changes even in a minor release.
- Could there be something broken/incompatible in your sound system? 
What sound system(s) does KDE have activated? Can you turn the sound 
system off and then try starting Rosegarden?

Other information that /may/ possibly be helpful: the result of the 
following commands:

$ emerge --info Rosegarden

$ cat /etc/make.conf

$ equery g rosegarden

Some other ideas:
- you could run "equery check rosegarden" on rosegarden or any of its 
dependences to make sure the files were installed correctly
- a rev-rebuild run might help, in case a dependency is broken
- Rosegarden does have a "debug" use flag. Perhaps if you rebuilt it 
with that enabled, some useful information might appear from debugging 
statements.
- You usually need to adjust some things in your system configuration to 
get meaningful backtraces, because the debugging info is stripped out by 
default. http://www.gentoo.org/proj/en/qa/backtraces.xml
