After revision 75ea4d59 (Merge branch 'use-qfiledialog-yue'), Krita's file dialogue (open, save and export) become the system's native instead of the former KDE's. Once opened, the dialogue will stay onscreen forever. it doesn't automatically disappear after an operation. Clicking on the close button does not close the dialogue either, causing major usability problem. Reproducible: Always Steps to Reproduce: 1. Open Krita 2. Menu -> FIle -> Open 3. Open a file 4. The file is opened, but the dialogue does not disappear. 5. Click the close button. 6. Nothing happens. Actual Results: The file can be opened and saved, but the file dialogue does not disappear, and it cannot be closed. Expected Results: The file dialogue should close itself automatically after an operation. It can be closed manually. You can drag the file dialogue off the screen as a workaround, but it's still kind of annoying.
It only seems to happen on Linux in non-kde environments -- I just tried in Gnome 3, and I could reproduce the weirdness.
I've reverted that merge.
After commit 855ec0fd & 5a0b64e9, the bug is still not fully fixed. The export dialogue won't close. Once opened, it dead locks the program. Desktop environment is Gnome 3.4 Fallback Mode.
Further report: This bug still affects both Save and Export file diaogue, but somehow different to what it was first discovered. 1. Save as or Export a file 2. Copy the file name 3. File dialogue freezes, but you can still move it 4. File dialogue cannot be closed.
Bah... I can confirm it. It happens again only in Krita, but in other Calligra apps, there's weirdness as well. In Krita the dialog hangs, but in Words, words hangs on close for some time, then ends with "QClipboard: Unable to receive an event from the clipboard manaer in a reasonable time"...
Something awful is happening with the clipboard: #0 0x00007f6f6fb917d3 in select () from /lib64/libc.so.6 #1 0x00007f6f71981998 in ?? () from /usr/lib64/libQtGui.so.4 #2 0x00007f6f719835a6 in ??

Looks complicated XD Good luck on nailing down the problem! :)
Git commit 82af13e2ccc20fd268fae5dc1f7c0043318a9daa by Boudewijn Rempt. Committed on 23/10/2013 at 20:37. Pushed by rempt into branch 'master'. Block the clipboard signals while showing the file dialogs The GTK native file dialogs, when you copy a file name (with ctrl-c) do something really horrible to the clipboard. This will cause a hang if the app connects to the QClipBoard signals. See: https://bugreports.qt-project.org/browse/QTBUG-11187 However, https://bugreports.qt-project.org/browse/QTBUG-32853 might still occur: that is, if the user tries to copy the filename, there'll be a delay on closing the app, and an error message on stderr: QClipboard: Unable to receive an event from the clipboard manager in a reasonable time M +41 -14 libs/main/KoFileDialogHelper.cpp http://commits.kde.org/calligra/82af13e2ccc20fd268fae5dc1f7c0043318a9daa
