Please let me know how I can be of assistance. The errors below or reproducible and consistent for me.

Code can be found here: https://github.com/ChrisLundquist/Handbrake-Network-Queue/tree/88c4ed38be1a871dfd5d012594710ea3dc0bb02c

This is a bug specific to 1.9 as the same code behaves as desired on 1.8.7

Obviously I cannot attach large copy righted files, but I would suspect you would encounter this errors with other similar large binary files.

I also get this error with a different file. It may be related.
NOTE: the below error happens 4mb into the file after it has already transfered 1.4GB of previous files.
wrong argument type Object (expected Data)
Occurs when transferring VTS_01_2.VOB of GLADIATOR

Attached is the last thing it reads from the socket before attempting to write it to the file.

I encounter the below error when transferring VTS_01_1.VOB of GLADIATOR

This only seems to happen with binary data files.

Out of curiosity I checked out and compiled the svn 1.9.2 branch.

All of my issues are resolved in the below version of ruby.
ruby 1.9.2p94 (2010-12-08 revision 30140) [x86_64-linux]

I commend you all on a job well done.

I look forward to the official release (and the update on the Ubuntu package) of 1.9.2p94
