Hi Nicolas,
Thanks for your answer! See below.

It's a consolation to know that I am not the only one seeing this. With the process I follow I have it every time, i.e. I can reliably reproduce it.

I am not sure I understand your last sentence. Could you please elaborate?

Right. Even if I don't debug but just choose the existing changes file in the popup menu the trunk update resumes and finishes.
However, there are several other problems:
1. The Environments package is dirty and has two ancestors (nice.47, cmm.51).
2. There are many corrupt files in the package-cache.
3. I get a strange variant of the "Error: Bits size mismatch" in CompiledMethodTrailer>>#encodeUsingZip when I execute the following script to find out the corrupt Monticello files from a Squeak workspace:
MCCacheRepository default allFileNames select: [:each |
[MCCacheRepository default versionInfoFromFileNamed: each.
false] on: Error do: [true]].
See the attached SqueakDebug.log for details. Again, I would be very interested if others can reproduce that error.
All this makes me wonder if I can safely use that image?
Cheers,
Bernhard
