[Qgis-developer] X server crashing QGIS

[Paolo Cavallini]

Hi all,
I'm testing the new plugin https://github.com/jawensi/DEMto3D
and I'm getting repeated QGIS crashes, e.g.:
=========================================================
Warning: QGraphicsScene::removeItem: cannot remove 0-item
Warning: QGraphicsScene::removeItem: cannot remove 0-item
Warning: QWidget::updateFrameStrut: No parent
Warning: X Error: BadImplementation (server does not implement operation) 17
  Major opcode: 20 (X_GetProperty)
  Resource id:  0x0
Warning: QWidget::updateFrameStrut: No parent
qgis.bin: Fatal IO error 11 (Risorsa temporaneamente non disponibile) on
X server :0.
Warning: QPixmap: It is not safe to use pixmaps outside the GUI thread
=========================================================

Warning: QGraphicsScene::removeItem: cannot remove 0-item
Warning: QGraphicsScene::removeItem: cannot remove 0-item
[xcb] Unknown request in queue while dequeuing
[xcb] Most likely this is a multi-threaded client and XInitThreads has
not been called
[xcb] Aborting, sorry about that.
qgis.bin: ../../src/xcb_io.c:179: dequeue_pending_request: asserzione
"!xcb_xlib_unknown_req_in_deq" non riuscita.
=========================================================
Any hint?
All the best.
