It does specify which OS you are using (Linux), but not your distribution.

ArchLinux isn't a support platform. It seems that your problem is the version of the XULRunner library in your 
distribution. IDE 4.6 only supports XULRunner 1.8.x - 1.9.0.x.

You can either update the library to one of those versions, or you can download a matching XULRunner version, extract it
 and have IDE use that specific version. To do so modify the "qde.ini" file under $QNX_HOST/usr/qde/eclipse directory, 
add the following line to the file:
-Dorg.eclipse.swt.browser.XULRunnerPath=/PATH_TO_YOUR_XUL_RUNNER
