Steps to recreate (Windows XP SP3):

PS C:\Development> mkdir testBranch
PS C:\Development> cd testBranch
C:\Development\testBranch
PS C:\Development\testBranch> bzr init
Created a standalone tree (format: 2a)
PS C:\Development\testBranch> edit test.txt [Save empty file]
PS C:\Development\testBranch> bzr add
adding test.txt
PS C:\Development\testBranch> bzr commit -m "Initial commit"
Committing to: C:/Development/testBranch/
added test.txt
Committed revision 1.
PS C:\Development\testBranch> bzr remove-tree
PS C:\Development\testBranch> cd ..
C:\Development
PS C:\Development> mkdir testCOLight
PS C:\Development> mkdir testCO
PS C:\Development> bzr checkout --lightweight testBranch testCOLight
PS C:\Development> bzr checkout testBranch testCO
PS C:\Development> cd testCOLight
C:\Development\testCOLight
PS C:\Development\testCOLight> bzr qbrowse
[Right-click test.txt, choose 'Show log'] -> produces attached traceback 'qbrowse-qlog-traceback.txt'

The bug does not appear when the same steps are followed in non-lightweight checkout 'testCO'.

Workaround in testCOLight:
PS C:\Development\testCOLight> bzr qbrowse -r -1
[Change revision from '-1' to 'wt:']
[Right-click test.txt, choose 'Show log'] -> shows log as expected
