Most recent build, most recent Chromium.
This likely has to do with the latest sourceforge outage; at least the problem originated from that time. It looks like it is caused by
a) running "svn update" when any script reports having a newer version than runs locally, or
b) manually trying to update a script with "svn update scriptname" even when it does not have a new version out.
The effect is that there is no real updating of the affected scripts (it just goes through "Validating repo... // Repo validated. // Updating scriptname... // /home/user/.kolmafia/svn/scriptname // Requests complete") and then the queue hangs itself up, meaning all other commands are blocked from being executed. The only solution at that point seems to restart mafia.
For me, this problem when caused by "a)" had to do with a Cheesecookie script (those I think are on sourceforge) but also one single Ezandora script (the Genie relay override which resides on github, like all the other Ezandora scripts). A clannie who also had the Genie overlay did not report having any problem with it in that way.
