POL script and logs

I'm was trying to upgrade my PlayOnLinux script for LoL, but I have I think
found a regression.
In 2.18, when I launch LoL, the splashscreen appear but after sometimes a
bugsplat append, when I switch to 2.17 the install progress dialog appear.

I have join the POL script (LeagueOfLegends test) and logs of LoL and POL (with
Wine output).

To reproduce the bug :
1 - Run the script with PlayOnLinux, select Download from North America or
Europe West, accept the TermsOfUse then let it work.
2 - Run with the shortcut. You are under Wine 2.18, the splash work but you
will got a crash dialog.
3 - In PlayOnLinux install Wine 2.17 x86, then in the virtual drive select Wine
2.17
4 - Run the shortcut, after Wine update you will look the splash and after the
download dialog spawn and work.

I don't have wait the full installation, made a test of regression or test
staging... but I think it has a problem. This is tested on a Ubuntu 17.04.

In logs, POL logs doesn't show unconventionnal things, in LOL there's some
"ERROR" while launching the Ux (process wich manage GUI).

In the hope to be usufull...
