[plt-scheme] Bugs in 349.100 (unable to use bug reporting tool)

Hi.
I compiled 349.100 from source on Ubuntu Dapper. I was about to use the
bug report tool in DrScheme, to report the fact that the *3m executables
hang on startup while CPU usage climbs to 100%. However, on clicking
"Submit Bug Report" I immediately got the following dialog:

path->string: expects argument of type <path>; given
"/opt/share/plt/doc"

 === context ===
/opt/lib/plt/collects/help/bug-report.ss:470:4: split-by-directories
/opt/lib/plt/collects/help/bug-report.ss:54:2: help-desk:report-bug
/opt/lib/plt/collects/mred/private/mrmenu.ss:185:17: command method in
basic-selectable-menu-item%
call-with-break-parameterization
/opt/lib/plt/collects/mred/private/lock.ss:40:2: as-entry

While I'm at it, I have a wishlist item, wrt the new build/install
process: Will there be support for an "uninstall" make target?

Thanks, and good luck with upcoming release.
