[Glass] GS 3.1.0.5: Fatal Internal Error, 5015, 15621, IO Error (RepRead Error)

It really seems this bug only occurs when tranlogging to /dev/null.

It's now two weeks later after switching tranlogs to real directories, and
this bug still has not resurfaced. Used to happen a handful of times a
week.

But on development test-suites etc. run about 3 times faster when
tranlogging to /dev/null.

Is there other way to get debug information on this while still
tranlogging to /dev/null?
