It can't be solved. An application cannot have more than one instance of BApplication. |

Xlibe can run even if a BApplication already exists. SDL1.2 can as well. SDL2 can't yet, but there's a patch to make this possible. Would it be possible to do the same in Qt? |

This came up when testing my new port of OpenCASCADE (no pull request created yet) with Xlibe.
When running some tests using Qt5 based tools, they crash when trying to create the Qt5 BApplication because Xlibe already created one before.
