Exception: The complexity of matching the regular expression exceeded predefined bounds.

Hello, With the last version of Grive2 I get the following error:

exception: The complexity of matching the regular expression exceeded predefined bounds.  Try refactoring the regular expression to make each choice made by the state machine unambiguous.  This exception is thrown to prevent "eternal" matches that take an indefinite period time to locate.

Version information:

• Current version: grive version 0.5.1-dev Jul 25 2018 22:36:34
• Last working version: grive version 0.5.1-dev May 6 2018 14:45:36

My system is Fedora 28 x86_64 with GCC 8.1.1 and Boost 1.66.

Do you use a complex griveignore?

No, I don't have this file. In my Google Drive folder, I have:

• .grive and .grive_state files
• .trash folder
• two symlinks to other folders on my PC representing the files I want to keep on Google Drive.

I recompiled grive2 with the last updates (that is, the ones you committed after July 25) and it seems that this issue has gone. Thank you for your time.
