Log message editor - took minutes to process keystroke

Dear Maintainers,

When entering a log message with the Commit or Edit Log Message dialogues,
the dialogue has sometimes frozen.
My impression is that this happens when the log message
contains a lot of bug-tracker codes or make-up (stars and underscores).
Such messages were no problem with Tortoise 1.4.*.

I did not have time yesterday to experiment much with when it happens,
and probably will not again till next Tuesday, 1 July.
I have found nothing about this in the mailing list, issue tracker or Web.

When one changes the log message,
the dialog shows an hour-glass and the text-fields are blanked out.
After waiting a few minutes the text is visible, correctly updated.
For much of the time while the dialogue is frozen,
a TortoiseProc process takes exactly 50% CPU (I think the system was dual-core).
That suggested an algorithm which does not always scale well.

A partially obfuscated log message which suffered this problem
on a revision with 92 changed paths was:
$ svn log -r 44788 | sed 's/[a-z]/x/g;s/[A-HJ-LN-Z]/X/g'

A partially obfuscated log message which I do not recall having had a problem

Tortoise was running on a Microsoft XP SP2 Dell (Dual Core?) system.
I had just installed TortoiseSVN 1.5
and subsequently CollabNet Subversion command-line client 1.5.
I had (of course) rebooted after installing Tortoise,
but not after the command-line client.
The Subversion server is pre 1.5.
I am can supply more exact configuration next Tuesday, should you wish.

I don't know how many open windows I had, probably about 25, including:
Firefox 2,
IBM WebSphere MQ 6.0 Explorer, Help,
MS Excel 2003,
MS Visual Studio 2005,
MS IE 6,
MS Outlook 2000 via Citrix,
MS DOS-box (several),
WRQ Reflection 13.0.
