"ERROR: exception.MemoryError" while checking out lightweight directory

[Michael Steele]

I have a '--no-trees' shared repository at E:\bazaar-repo and a branch holding my ebook collection at E:\bazaar-repo\ebooks. There are also other branches within this repository, and they all have their own lightweight checkout under E:\. I had all of this stored on a FAT32-formatted external hard drive, and everything has been working fine.

Well I decided to reformat this hard drive as NTFS, hoping to resolve an issue with file names containing non-ascii characters. I did this by copying the contents of the drive onto my desktop, reformatting the drive, and then copying the entire /bazaar-repo folder back to the drive.

Here is a log of the error while trying to restore my lightweight checkouts. There was about a 1 minute delay between entering the command and receiving the error. During that time, task manager reported that the 'bzr' process was eating up 1GiB of memory:
