The same bug happens in Ubuntu 18.04. It doesn't matter if wayland or xorg is being used. It's consistent. When the theming engine is disabled, the Marketplace fails to open. It's a new bug of Eclipse Photon. Eclipse Oxygen shows the marketplace fine in both Windows and Linux when the theme is disabled. I suggest to change the title of this bug to be more meaningful. Something like "Marketplace fails to open when the theming engine is disabled" Here is a piece of the log on my machine showing where the nullpointer occurs. It's identical to the previous log, apparently ...

Hey, everyone. Thanks for the report. The issue is fixed in current 1.7.2 milestone builds, which you can get from http://download.eclipse.org/mpc/nightly or http://download.eclipse.org/releases/2018-09. I will push out the final release as soon as RC1 feedback for the Eclipse 2018-09 release is in without any blockers - so, roughly by the end of next week. *** This bug has been marked as a duplicate of bug 536524 ***
