I get:

Powerbook-2:org.openembedded.dev.avr32 koen$ mtn changelog MAINTAINERS
mtn: warning: _MTN/monotonerc:117: attempt to concatenate field '?' (a
nil value)
mtn: error: Call to user command changelog (lua command:
output_changelog) failed.
Powerbook-2:org.openembedded.dev.avr32 koen$ mtn --version
monotone 0.37 (base revision: c21eefc002b8f9c430e9f4cc16c4af7b852f54ec)

The error is from this portion (line numbers added):

115  changelog_revs = split_string(changelog_revs, "%s*(%S*)%s+")
116  result,changelog_revs = mtn_automate("toposort",
unpack(changelog_revs))
117  changelog_revs2 = release_revs[#release_revs] .. " " ..
changelog_revs .. " "
118  changelog_revs = table.reverse(split_string(changelog_revs2,
"%s*(%S*)%s+"))

any idea what is causing this error?

regards,

Koen
