+Subject: address a rare crash/hang on exit |
27 |
+ |
28 |
+Under rare circumstances Qt would attempt to deliver signals to stale |
29 |
+style instances, or leave orphaned style instances after unloading the |
30 |
+plugin. This is addressed by disconnecting the (currently only) signal |
31 |
+originating from an external application and the plugin now ensures it |
32 |
+leaves no orphaned style instances behind. |
33 |
+Also, moves the code handling pre-exit disconnection to a subclass. |
34 |
