[Touch-packages] [Bug 1571158] Re: Crash in QXcbWindow::setParent() due to NULL xcbScreen()
Dear Martin, I purged landing-016 ppa, re-compile my application, and it crashes as expected. Then I enabled pre-released updates, updated the Qt packages to version 5.5.1+dfsg-16ubuntu7.1 from proposed, re-compile again, and the crash disappeared. So, yes, thank you: this package fixes the crash for me! For the details, the application is camitk-imp (available in the package "camitk" version 4.0.0, which did not make it to Ubuntu 16.04), a medical image analysis and modeling software based on Qt and VTK. My machine is a (rather old) Dell M6400 laptop. Let me know if you want me to use the test case provided by Mitsuya as welle or need more information about my testing or if you need me to do further testing. Thanks to everyone for this fix and to Martin for the detailed instruction on how to test and report this package! -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to qtbase-opensource-src in Ubuntu. https://bugs.launchpad.net/bugs/1571158 Title: Crash in QXcbWindow::setParent() due to NULL xcbScreen() Status in qtbase-opensource-src package in Ubuntu: Fix Released Status in qtbase-opensource-src source package in Xenial: Fix Committed Bug description: [Impact] Application crash in certain situation.

[Touch-packages] [Bug 1571158] Re: Crash in QXcbWindow::setParent() due to NULL xcbScreen()
Thank you again for you work and your answers. I hope that the updated package will pass all the required Q I understand (and agree with the fact) that it is very important to make sure that there is no regression. Let me know if I can be of any help. In the mean time, would it be ok to use your ppa? Or do you recommend something else? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to qtbase-opensource-src in Ubuntu. https://bugs.launchpad.net/bugs/1571158 Title: Crash in QXcbWindow::setParent() due to NULL xcbScreen() Status in qtbase-opensource-src package in Ubuntu: Fix Released Status in qtbase-opensource-src source package in Xenial: Confirmed Bug description: [Impact] Application crash in certain situation.

Thank you for the detailed instructions... and the fixed packages! Version 5.5.1+dfsg-16ubuntu7.1 solved the problem on Xenial. There is no more crash!

[Touch-packages] [Bug 1571158] Re: Crash in QXcbWindow::setParent() due to NULL xcbScreen()
Any chance of fixing this in xenial as well (as suggested by comment #2)? At the moment our application crashed on xenial at startup due to a problem in XcbWindow::setParent. Same code works fine on debian unstable and testing. I don't know if the fix provided in 5.5.1+dfsg-16ubuntu10 will work for our code, but I will be happy to test (if there is a way to check 5.5.1 +dfsg-16ubuntu10 on xenial, let me know). Thanks to all if it is possible to fix this on the last LTS, that will be a big help. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to qtbase-opensource-src in Ubuntu. https://bugs.launchpad.net/bugs/1571158 Title: Crash in QXcbWindow::setParent() due to NULL xcbScreen() Status in qtbase-opensource-src package in Ubuntu: Fix Released Status in qtbase-opensource-src source package in Xenial: Confirmed Bug description: [Impact] Application crash in certain situation.
