Missing argument in user/1

I'm seeing this too. I'm not sure what the consequence is though.

Checking that line it is the function signature for hook_user. Looking at the docs for hook_user - http://api.drupal.org/api/function/hook_user/5 - it seems that

1) this function wasn't taking some of the args by reference which is probably should
2) this function wasn't using a default for $category so when the optional $category parameter was passed, php wasn't able to default it and instead complains.

I'm not sure that this is critical or even causes any problems, necessarily, but the attached patch should fix it (I haven't tested it yet, I'll be watching my logs to see if the error comes up again).

@int - please test out the patch and respond back if it solves the problem for you (and also what the problem you experience is).

+1 for this patch

fixed the error for me.

rtbc baby. ;)

How to apply patch?

But this patch doing nothing. $array and $user are not updated anywhere, so it not make sense to make them referenceable.
The error is related to 4th argument what's set in latest snapshot.

5.x version is no longer supported, try 6.x
