Indeed linum.el suffers from various corner case problems.  Maybe this
one is fixed in Emacs trunk, or maybe it can be fixed.  But the
implementation technique used by linum.el has proved over the years to
lead to many such corner case issues.

I suggest you try out nlinum.el (available in GNU ELPA) which provides
basically the same functionality as linum.el but using a different
implementation approach, which is more robust.
