v5.1.68 still works with a rebuild. the originally built package (5.1.68-1) from november threw the same error, which went away with a package rebuild (in may). i can;t get rid of the undefined symbol error in the latest version. yet.
Edit:
@pgoetz the problem will have to be fixed upstream. there is a reference to QMutexPool::globalInstanceGet in the masterpdfeditor source itself, vs. a library referenced by the app. i'm also finding online references to Qt5 changes where QMutexPool is/was to be removed. the newest version of the Qt5 API (therefore Qt libraries) no longer provides access to a QMutexPool class. we're going to need a new release from above before this'll work. v5.1.68 doesn't have the same reference and does still work.
