Comment 17 Martin Stransky 2007-08-20 11:36:59 UTC
Behdad, could you please check this firefox-1.5-pango-underline.patch?

Comment 18 Akira TAGOH 2007-08-20 14:31:59 UTC
the proposed patch looks not good to me. it may fixes this issue but it will
introduces other issue on other place. actually "start" and "end" expects
pointing to the start position and the end position and it has to be a positive
value.  So something else is still wrong...

Comment 19 Martin Stransky 2007-08-20 14:37:19 UTC
Eh, I'm not sure if the usage of unsigned types can ensure the positive values
:) Anyway, feel free to fix the firefox-1.5-pango-underline.patch as you want....

Comment 25 Akira TAGOH 2007-09-05 12:50:08 UTC
Sorry for taking a long time. After some investigations, the negative values was
likely to appear without any pango patches in our package. since I haven't
touched the core logic around it, Martin's patch looks correct then.  Thanks
Martin for the patch and sorry for false alarm.

Comment 26 Martin Stransky 2007-09-05 12:58:41 UTC
aha, okay, I'll update the current patch then. thanks.

Removing Securiy keyword; I see no security implications. In case you aware of
any, please let me know.
