Trying to change multiple bugs at once gives the error: Can't call method "in_group" on an undefined value at Bugzilla/Bug.pm line 1230. That means that somehow $self->{'who'} is undefined in the bug object at some point, for some reason, during process_bug.cgi.

What is broken is the moving of products. This is because $bug is initialized with a bugnr that does not exists. This causes $self->{'who'} not to be set. Patch just moves the initialization of the code that sets $self->{'who'} up (before returning). Haven't tested if this causes assumptions in other parts of the code to be broken.

Comment on attachment 227845 [details] [diff] [review] patch, v1 >+ if ((! defined $bug_id) || (!$bug_id) || (!detaint_natural($bug_id))) { Nit: even better, write: unless ($bug_id && detaint_natural($bug_id)) { I know this is how the old code is. But this could easily be fixed on checkin. r=LpSolit NB: The funny thing is that I fixed the problem on my side, and when I called "cvs diff", I realized we had the same patch. ;) That's why I renamed your patch from "untested patch" to "patch, v1", because I tested it even before looking at yours.

Reassigning the bug to bkor, as he was faster than me. ;)
