Hello all,

Running with a local rebuilt package deepin-qt5dxcb-plugin
the crash does not happen.

Looks like there is currently an attempt to rebuild this
package in the archive (1.1.11-1+b1) going on, but that
seems to have not yet succeeded. [1]

This FTBFS bug [2] against Qt 5.11.1 in experimental is
maybe related to the rebuild attempt.

Kind regards,
Bernhard
