[TxMt] latex bundle: citation completion hangs

[Bilal Barakat]

Hi,

when I select 'Citation Based on Current Selection' I get a spinning  
beach-ball. Activity Monitor shows a ruby process eating 99% CPU.  
When I quit it, the following is inserted in my TM document:

/Applications/TextMate.app/Contents/SharedSupport/Bundles/ 
Latex.tmbundle/Support/lib/LaTeXUtils.rb:134:in `parse_bibfile':  
Interrupt
	from /Applications/TextMate.app/Contents/SharedSupport/Bundles/ 
Latex.tmbundle/Support/lib/LaTeXUtils.rb:115:in `map'
	from /Applications/TextMate.app/Contents/SharedSupport/Bundles/ 
Latex.tmbundle/Support/lib/LaTeXUtils.rb:115:in `parse_bibfile'

	from /Applications/TextMate.app/Contents/SharedSupport/Bundles/ 
Latex.tmbundle/Support/lib/LaTeXUtils.rb:214:in `each'
	 ... 8 levels...

Latex.tmbundle/Support/lib/LaTeXUtils.rb:203:in `recursive_scan'

Latex.tmbundle/Support/lib/LaTeXUtils.rb:254:in `cite_scan'

Latex.tmbundle/Support/lib/LaTeXUtils.rb:63:in `get_citations'
	from /tmp/temp_textmate.MQuf7X:8

I think it worked correctly at some point in the past.
Any ideas on what's going wrong here? Any help would be much  
appreciated.
