I think it's actually two different issues that come up here:
* bzr-svn should report a clearer error rather than a backtrace
* fetch should be continuable
The first should be fixable quite easily. Unfortunately, it'll also mean hiding the backtrace for genuine bugs in bzr-svn since the exception raised by svn is very generic.
The second is actually a bug in bzr itself, already reported as bug 116148.
Thanks for taking the time to report this bug.
