Description of Problem: if the 'URL' field in the bug report form has a
long value, Bugzilla chokes when you try to commit the bug.

Version-Release number of selected component (if applicable): 
whatever bugzilla.redhat.com/bugzilla/ is running


How Reproducible: go to bug report page and enter a nice long URL in the
URL field.  For example, I was trying to file a bug report with the URL

https://bugzilla.redhat.com/bugzilla/buglist.cgi?email1=&emailassigned_to1=1&email2=&emailreporter2=1&changedin=&chfieldfrom=&chfieldto=Now&chfieldvalue=&short_desc=&long_desc=com_err&bug_file_loc=&status_whiteboard=&cmdtype=doit&newqueryname=&order=Bug+Number+Ascending&form_name=query

Then fill in any mandatory fields and press 'Commit'.

Actual Results: got to post_bug.cgi with the error message:

Content-type: text/html
Software error:
DBD::Oracle::st execute failed: ORA-01401: inserted value too large for
column (DBD ERROR: OCIStmtExecute) at globals.pl line 225.

For help, please send mail to the webmaster (bugzilla), giving
this error message and the time and date of the error.


Expected Results: I expected the bug to post correctly even with a somewhat
long URL.  Or in the worst case, Bugzilla should fail cleanly and say
'the URL you've chosen is too long'.

Additional Information: you might say that nobody in his right mind would
make URLs that long.  But this particular example is a URL from Bugzilla
itself!  Bugzilla can dish it out, but it can't take it...
