OUCH: rolling back the collects a week doesn't do it:

Welcome to DrScheme, version 4.2.1.7-svn13aug2009 [3m].
Language: Module custom; memory limit: 256 megabytes.
Module Language: invalid module text
. scheme/lang/compiled/drscheme/errortrace/reader_ss.zo:1:0: read (compiled): code compiled for version 4.2.1.6, not 4.2.1.7

Interactions disabled.

What the hell does this mean?

I tracked down one obvious error (locate-frame instead of locate- file in private/ somewhere) but I will leave it to you. Thanks.

(It was supposed to be a method of the frame-group, fwiw.)

I think that the error is coming from the error-display-handler.
Generally speaking, that code is called in strange places, so needs to
not raise errors.

Switching to Module in drscheme immediately produces this error message

Welcome to DrScheme, version 4.2.1.7-svn27aug2009 [3m].
Language: Module; memory limit: 256 megabytes.
Module Language: invalid module text
send: no such method: locate-frame for class: %

and it disables all buttons except for STOP. Clicking stop doesn't help
the least.

I get the same error. Some more notes:

By a combination of kills and breaks (a final break seems necessary...?) I was able to kill the evaluation. When I switched the language to Pretty Big, I got a "read found code compiled for 4.2.1.6, wanted 4.2.1.7" (paraphrased because it is no longer in front of me). I have no idea what code in
particular it's taking about.

My conjecture is that Robby's commit (r15795) is responsible for the error message that actually gets shown ('locate-frame' occurs nowhere else in the collects, as far as I can tell), but there seems to be an underlying
problem. That is, there's an error reporting the real error.

I had run a full setup-plt immediately before starting DrScheme, so
somewhere code is not getting recompiled. I'm currently in the middle of a
"setup-plt -c; setup-plt" cycle.
