We've been checking Qt revdeps and noted some potential dependency improvements:

* /opt/dropbox/PyQt5.QtCore.so links to /usr/lib64/libQt5Core.so.5 (dev-qt/qtcore:5)

* /opt/dropbox/PyQt5.QtQml.so links to /usr/lib64/libQt5Qml.so.5 (dev-qt/qtdeclarative:5)

* /opt/dropbox/plugins/platforms/libqxcb.so links to /usr/lib64/libQt5XcbQpa.so.5 (dev-qt/qtgui:5[xcb]

* dev-qt/qtquick1 appears to be unused

Wait a second, libqxcb.so is a Qt plugin, and the other two .so files look like PyQt5 libraries... is dropbox bundling all this stuff? Is it possible to unbundle them?
The bundled plugin is especially alarming, because version mismatches can easily cause horrible runtime crashes (or maybe it doesn't get loaded because the system-wide plugin is preferred).

Yeah, dropbox bundles all of this :(. I cant for the life of me get it to run using the system PyQt5. even symlinking the .so files one by one doesnt load cuz of some unicode issue. Dropbox is some python thing that is compiled into an elf. LD_LIBRARY_PATH and those kinds of things dont work either.

The plugin does not seem to be required and I am removing it in 5.3.18.

Does this bug still need to be open?
