This is similar to bug 36172.
In any diff view, if I click any of the links in lines like:
"+10⇧ ... skipped 198 common lines ... +10⇩"
then one white line appears and the following kind of error is printed on the console:
Uncaught Class$S1362: Exception caught: Array index ### out of range
Using the context size option from preferences work though.
Expected result:
More context would appear as it used to.
Version: unspecified
Severity: normal
