unclean url concat

We have two projects in Jira - PROJECT1 and PROJECT2
there was an issue PROJECT1-123
it was moved(using 'Move' feature) to PROJECT2-456
then, if I'm entering URL http://jira/browse/PROJECT1-123 browser redirects to http://jira/browse/PROJECT2-456
That's ok
But if I'm opening http://jira/browse/PROJECT1-123?page=all
it is redirecting to
http://jira/browse/PROJECT2-456?rc=1page=all
(no ampersand)
and if I'm trying to open http://jira/browse/PROJECT-123?rc=2rc=1
I'm getting
java.lang.NumberFormatException: For input string: "2rc=1"
