With the last security updates the glibc package was updated, but there is no matching glibc-debuginfo package in the DEBUG repo. This renders openSuSE 11.2 at the moment hard to use for development, since valgrind cannot be used - it complains about missing symbols.
To the maintainers:
The easiest way out would be not to strip the .so. otherwise please make sure that always a matching debuginfo package is generated and put to the repo when an update is published.
