[Libreoffice] LoadComponentFromUrl misuse lead to crash

Hi Caolan

i checked under windows, ok "unsupported url"

seems that the only persons that reproduces the crash are under ubuntu
(10.00 for me, 11.10 for jbfaure)

you and cedric (i assume you run some linux ;) ) had the expected
message (at least no crash)

the bt was in my original message (rather old). seems an infinite loop
regarding titles
i paste it there

imho, the problem is before the crash, the url being not detected as invalid

feel free to ask if you need more details

thanks a lot

Laurent
