Build Identifier: 0.9.0.201007291519

When selecting a large commit in the History view, I observe a generic "An error has occured" dialog with an unhelpful hash value.

The commit was extremly large (relocation from another source code management system). In the error log there is an LargeObjectException. Regardless whether this exception may happen at all or not (see bug #321097), the UI should at least behave more user friendly in this case.

In the error log, there is the following stack trace:
