Ok then, please reinstall the kdesvn(-kio-plugins) packages from unstable and if it fails again run it in valgrind [1]. Hopefully that reveals something useful. Quoting some comments from the d-d mailing list: <<<< On amd64, the only two reasons for a SIGBUS are (a) as a result of mmap, or (b) as a result of bad hardware. Assuming (a) for now, mmap(2) says: SIGBUS Attempted access to a portion of the buffer that does not cor‐ respond to the file (for example, beyond the end of the file, including the case where another process has truncated the file). Note that on other architectures, SIGBUS can also mean an unaligned access. It looks like, according to the strace, the KDE plugin loader is loading libkdesvnpart.so (*hopefully* through libdl/ld.so), and that once it's loaded the stack/data portions, something accesses the "gap" and the kernel raises a SIGBUS. It's really hard to tell what's going on here, but it could be a corrupt binary, a bug in the code that just happens to access that location, a bug in ld.so, or something else entirely. <<<< In case, kdesvn should work now after reinstalling, maybe the binary was simply corrupted the first time.
