Hello, If you are using sid, and find some (non-kde) c++ applications crashing since the c++ ABI transition, then it could be (at least in my case it was) due to arts, namely artsdsp. I have 2 examples of applications I used to run through artsdsp, and that crashed a lot, it's firefox 1.5beta and skype. Since I removed artsdsp from their command line, they work. just FYI... best regards and a nice weekend!
