Bug#766241: gnome: dist-upgrade on 20-Oct lost gnome pixbufs and several tweak settings reset

[Jim Cobley]

Hi Michael

I did the dist-upgrade late on the 20th - about 10 hours after the 
updates for that day had been set - going from the date stamps shown 
whilst the "update" was downloading. So I would assume that this problem 
had been introduced on that day - rather than being fixed!

The only report by dist which has been happening for several days now is 
it complains about an issue with "jpeg progs" (sorry can't remember the 
exact message. Certainly don't remember seeing the message that you mention.

It is tricky deciding what package it should be filed against - I knew 
nothing (still don't know much) about the internals of Gnome.

I booted under another system and searched - I ran into a report on 
another distribution which mentioned 3 possible fixes and I was lucky it 
worked. One of the main reasons for filing the report was to ensure tat 
the fix was there on Debian for others if they had the issue. Problem 
did not recur for me and I generally do daily dist-upgrades.
