Description
Hello,
I received this backtrace when trying to login to an svn server over an ssh -Y
X forwarded connection using the kwallet plugin.
When the kwallet application failed to collect the credentials because it did
not want to run successfully in this environment, svn experienced a segfault.
At the time I was running Ubuntu 12.04 LTS with latest updates, but there is
not a libsvn-dbg package with debug symbols so I couldn't get better data on
the crash.
Sadly good old objdump did not help either because the symbol offsets from the
svn binary and libsvn_auth_kwallet-1.so did not line up. I suspect it could be
due to dlopen or other runtime behavior.
However I figured it would be good if this could be saved for posterity in
case somebody else saw it, or had a better SVN environment for reproducing it.
The workaround is to log in using plain SSH and perform the svn checkout via
CLI entirely, which prevents kwallet-based credential prompting and hence
prevents the crash.
Regards,
Matthew.
