Package: libvte4
Version: 1:0.12.2-4
Severity: normal
If your gnome-terminal's window is full of email addresses,
gnome-terminal starts to take 100% cpu as soon as your mouse is put over
the text.
To reproduce it, open a gnome-terminal, maximise it and enter the
following at the prompt :
$ python -c "print(['[EMAIL PROTECTED]' for i in range(500)])"
You end up with a window full of email addresses and when your cursor
pass over the window, gnome-terminal take 100% for a while.
If you run it inside gdb and interrupt it, you'll get the following back
trace :

Having looked at vte_terminal_match_check_internal in src/vte.c, it
seems that every token inside the buffer is search against the list of
registered regexps.
