Bringing this from users@ to dev@. Rolf Campbell discovered an assertion failure that I think might shed some light on other assertion failures we've been hearing about from time to time.

I would like to debug this properly but am running into various nonsense. For example, I haven't figured out how to run it under gdb since svn is being called through the libtool script; if I configure with --disable-shared the build fails. Sorry, I don't have the details atm. I'll have to rerun it later. Out of time for today but I will try to resolve these issues soon. What I do know so far is the reason that check_can_add_node() fails the assertion check: copyfrom_url is not canonical. When I run the above repro script at /home/nate/ramdrive, the non-canonical URL is "file:///home/nate/ramdrive/test/". Cheers, Nathan
