Package: libpango1.0-udeb
Version: 1.44.7-3
Severity: grave
Tags: d-i
Justification: renders package unusable
X-Debbugs-Cc: debian-boot at lists.debian.org


In the “better late than never” department… I've completed a debugging session
that shows that upgrading libpango1.0-udeb from 1.42.4-8 to 1.44.7-3 hangs the
installer in various situations.

Interestingly, it doesn't *always* do that.

 - I know for sure this upgrade is responsible for the rescue mode
   breakage *under some locales* tracked at:

   e.g. getting a shell into the system to be rescued works fine in
   French or in German, but not in English (which hasn't any crazy fonts
   or glyphs compared to the two other ones).

 - It seems to a kind user performing many tests that this could be
   linked to the actual hardware configuration:

   (See the “For short […]” conclusion, it's priceless.)

   I'll be trying to get more results from Étienne.

 - I'm *not yet* certain this also triggers direct failures for Netinst
   images for several languages, tracked at:

   but I have a rather strong suspicion, as mentioned in:

   I'll try to confirm this in the next few days.

Chris Hofstaedtler provided some perf data, which might help figure out
what's happening for someone who's knowledgeable about pango internals:

Please keep debian-boot at lists.debian.org in the loop when replying, and
thanks for your help!
