rehoo crashes with exception on non-exhaustive pattern match

[gilligan]

Running "rehoo -c 16 -j 8" in my databases dir yields the following error:

This is an issue in hoogle that I've also run into many times. Which version of Hoogle are you using?

[gilligan]

Ah yeah it's rather obviously an issue with hoogle itself. Sorry. I am using version 4.2.32 - Any ideas how to work around this ? All I want is to search all packages and not just the default set.. sigh ;-)

[jwiegley]

Well, what I do in this case is to change All.hs and have it just print an error instead of throwing an exception. When this happens it's actually usually benign.

It's happening because one of your .hoo files has invalid data in it, and it's hard to see which one when using rehoo because of the way it combines them in groups.
