[mpc-dev] MPC for Mars M5 issue with Linux/GTK3

Hi everybody,

Please note that due to an unforeseen structural change in SWT for GTK3, the
MPC contribution to Mars M5 doesn't work properly with GTK3.

When using Mars M5 with Linux GTK3, you will notice that the "Recent",
"Popular" and "Installed" tabs in the Marketplace Client remain empty.
"Search" and "News" should work as expected, so MPC is still usable.

As a workaround for a full MPC experience, you can switch to GTK2 by setting
the SWT_GTK3 environment variable before starting Eclipse:

$ export SWT_GTK3=0
$ ./eclipse

Since a possible workaround for Linux would have broken Windows and Mac due
to another bug, and because it warrants more careful testing to avoid
unintended side-effects, we decided to go with the GTK3 breakage for M5.

The MPC issue is tracked in [1]. The underlying SWT issue is tracked in [2]
and has been fixed as of yesterday evening. So has the Windows/Mac bug
preventing a workaround, tracked in [3]. I'll publish a fixed MPC build in
the next days, so all should run smoothly for M6 again.

Best,
Carsten
