lp:~dirk-miriup/rescuetime-linux-uploader/chrome-test might be less table than lp:~dirk-miriup/rescuetime-linux-uploader/bug-674122

After switching from lp:~dirk-miriup/rescuetime-linux-uploader/bug-674122 to lp:~dirk-miriup/rescuetime-linux-uploader/chrome-test I frequently see errors similar to the following:

X Error of failed request: BadWindow (invalid Window parameter)
  Major opcode of failed request: 21 (X_ListProperties)
  Resource id in failed request: 0x640920a
  Serial number of failed request: 12
  Current serial number in output stream: 12
None () now focused (Extended info: None)

After that capturing information from windows is not reported anymore (and may not be working anymore). The only other time this session reported something about windows after the above error was:

X Error of failed request: BadWindow (invalid Window parameter)
  Major opcode of failed request: 21 (X_ListProperties)
  Resource id in failed request: 0x6c06154
  Serial number of failed request: 12
  Current serial number in output stream: 12
