In order to build wallch you indeed will use 'qmake', but first make sure to install all the packages listed on the Build-Depends section of debian/control file.
I just want to say that I believe that it may not be Wallch to blame as the same code runs perfectly fine in Ubuntu 14.04 LTS and maybe Mint's 17 indicator drawer isn't completely stable yet.
Thanks for trying to resolve the problem.

The latest Wallch source can be obtained using bzr branch lp:wallpaper-changer
