Package: libqtgui4 Version: 4:4.5.2-1 When QClipboard::setText(QString, QClipboard::Selection) is called "late" (meaning at least from an event handler, but I haven't narrowed it down completely) retrieving the selection in another client doesn't work. More particularly, ownership of it gets set, but other clients cannot retrieve the data.
I've attached a small program which demonstrates the problem. After launching, a window containing a button will show up. Before pressing that button, retrieving the primary selection via "xsel -v -v -v -v" displays something like: xsel: Window id: 0x5e00001 (unmapped) xsel: Timestamp: 3983411207 xsel: Maximum request size: 4000 bytes xsel: Got window property: requestor 0x5e00001, property 0x321, target 0xf4 UTF8_STRING, length 12 bytes Hello world! That text was set by calling QClipboard::setText in main. After pressing the button, it changes to: xsel: Window id: 0x5e00001 (unmapped) xsel: Timestamp: 3983455616 xsel: Maximum request size: 4000 bytes xsel: Conversion refused xsel: Conversion refused This time, the selection was set by calling QClipboard::setText in a slot attached to the button's clicked() signal. I've traced through the execution of the event handler as well as I can in gdb. At line 1020 of qclipboard_x11.cpp, something very odd happens in the "bad" case that I cannot explain. It suddenly jumps down past all the bits which actually put the data in the event to line 1109, sending an empty reply to the reqesting client. This behaviour is new. In previous versions of the qt package, other clients were able to retrieve the selection as expected in all circumstances.
