Hi,

I’ve put my gem command into an unusable state:

~$ gem list --r

\*\*\* REMOTE GEMS \*\*\*  
Bulk updating Gem source index for: [http://gems.rubyforge.org](http://gems.rubyforge.org)  
ERROR: While executing gem … (NoMethodError)  
private method `scan’ called for #YAML::PrivateType:0x3849600

I’ve previously removed source\_cache, with source\_cache in place, I get  
the following

\*\*\* REMOTE GEMS \*\*\*  
Need to update 2 gems from [http://gems.rubyforge.org](http://gems.rubyforge.org)  
.ERROR: While executing gem … (URI::InvalidURIError)  
bad URI(is not URI?):  
[RubyGems.org | your community gem host](http://gems.rubyforge.org/quick/activerecord-jdbc-#)gem::version:0xa53ac84.gemspec.rz

Could anybody point me to a solution?

TIA,  
Patrick

Actually, this is a global state, due to my recent release. In some way,  
this have corrupted the source index. Sadly, RubyForge blows when I try  
to remove the erraneous file…
