Commands in log dialog fail if started for an url instead of a working copy path

[GoogleCodeExporter]

When the log dialog is shown for an url instead of a working copy path, some 
commands can throw an error message.
This can happen is the log dialog is started e.g. from the repository browser.

First reported here:

when open log dialog from REPBrowser,the following operation failed.On the 
other hand,all operation seems ok when i open log dialog from local checkout 
directory.
1.show log in the changed file list ,error message is :
---------------------------
TortoiseSVN
---------------------------
No path or pathfile specified on the command line!
---------------------------
OK

after this message,nothing more happen.
2."browser repository"、"get merge log" in the changed file list,error message 
is same with no.1
3."save revision to ..." in the changed file list ,error message is very long 
,as following :
---------------------------

Please take the time to report this on the Subversion mailing list
with as much information as possible about what
you were trying to do.
But please first search the mailing list archives for the error message
to avoid reporting the same problem repeatedly.
