Reproduction steps:

1. Go the the "File Status" tab
2. Select "All files" from the dropdown
3. Use the text filter box to find a particular file
4. Right click on the file and select "Log Selected". This works fine.
5. Use the text filter to find a different file
6. Right click on the file and notice that "Log Selected" is disabled

The only workaround is to empty the text filter and then type the new filter.
