Hi all,

I get the following error when I try to export a specific history to file: - - [07/May/2012:18:01:08 +0200] "GET /history/export_archive HTTP/1.1" 500 - "http://galaxy.immunbio.mpg.de/"; "Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv: Gecko/20111108 Fedora/3.6.24-1.fc14 Firefox/3.6.24" Error - <type 'exceptions.TypeError'>: <galaxy.tools.parameters.basic.UnvalidatedValue object at 0x8ba67d0> is not JSON serializable

I tracked the problem down to a single bed file. I copied it into a new empty history and I can still not export this history to a file. This file doesn't have any special characters in either its name, info or annotation. I can't find anything special about this file...

Any help is greatly appreciated!
