No idea whether it's the same bug or not -- I'm not even going to attempt to reduce until we know it's clearly a different problem -- but I also get this assertion when clicking on letters on the following page:

http://www.sirdarckcat.net/cskg.html

Something's weird about the page that apparently makes it impossible to run again -- maybe cookies, maybe cache, although force-reload did nothing -- so you may need a new profile to be able to replay the assertion after a first time through.

Now I just get

WARNING: nscoord addition capped to nscoord_MAX: '(PRInt64)a + (PRInt64)b < (PRInt64)nscoord_MAX', file ../../dist/include/gfx/nsCoord.h, line 156

(This one was changed from an assertion to a warning in bug 408754.)

I'm not marking this bug as WFM because I don't think it makes sense for this testcase to trigger the warning.
