It looks like there is a message with a broken format. You said it was was
entering a folder, but it'll be when opening a message. Presumably you have
opted to have a message automatically opened.

Go to /Configuration/Preferences/Display/Summaries, select the Message
List tab, uncheck all the 'open message when selected' options.

Turn on the Number column in the message list.

Locate the problem message by opening the right message. This will correspond
to the option 'Set message selection when entering a folder', on the same
page as previously mentioned.

Then find the message file on your file system, and attach it to a message.
Send that message to me, off-list, so I can try to work out the problem and
the fix.

This all supposes that my broken format theory is correct.

with regards
