Test script for Tom to try


I suspect that it has something to do with this snippet from the logs:

[2236] dbg: uri: html uri found,
mailbox:///C|/Documents%20and%20Settings/Administrator/Application%20Data/Thunderbird/Profiles/wdnmem55.default/Mail/Local%20Folders/Inbox?number=29229479∂=1.5&filename=spacer.gif

[2236] dbg: uri: cleaned html uri,
mailbox:///C|/Documents%20and%20Settings/Administrator/Application%20Data/Thunderbird/Profiles/wdnmem55.default/Mail/Local%20Folders/Inbox?number=29229479%e2%88%82=1.5&filename=spacer.gif

[2236] dbg: uri: cleaned html uri,
mailbox:///C|/Documents%20and%20Settings/Administrator/Application%20Data/Thunderbird/Profiles/wdnmem55.default/Mail/Local%20Folders/Inbox?number=29229479∂=1.5&filename=spacer.gif


The actual URL-like string in the body is

mailbox:///C|/Documents%20and%20Settings/Administrator/Application%20Data/Thunderbird/Profiles/wdnmem55.default/Mail/Local%20Folders/Inbox?number=29229479&part=1.5&filename=spacer.gif


Notice how the URI parser changed 29229479&part= to 29229479%e2%88%82= and
29229479∂=

That seems wrong in any case.

Is it concevable that Tom's setup has a problem with unicode characters? Wasn't
there something about it that was a problem in 5.8.0 that was fixed in some
later 5.8.x?

I'm attaching a short test script that I think does the same pattern match that
SpamAssassin seems to be doing in this case. Tom, will you see if it crashes
your perl?
