Hi, there are at least 3 issues in Rawhide (some or all of which also affect the Fedora 25 branch!) making both QupZilla (the main user of QtWebEngine) and Chromium fail to start up. One of them has no known workaround. And from my investigation, none of them appears to actually be IN QtWebEngine or Chromium code: 1. https://bugzilla.redhat.com/show_bug.cgi?id=1363914 [abrt] qupzilla: base::debug::BreakDebugger(): qupzilla killed by SIGABRT Apparent cause: selinux-policy Reason: because "setenforce 0" works around it F25 affected?: unknown Workaround: sudo setenforce 0 2. https://bugzilla.redhat.com/show_bug.cgi?id=1347436 fedora-import-state sets incorrect mode for /dev/shm when dracut places it in /run/initramfs/state (causes various things to break, inc. webkit and Boxes) Apparent cause: initscripts Reason: as per the bug report F25 affected?: yes (the bug was reported against F25, but it also happens in Rawhide) Workaround: sudo chmod a+w /dev/shm 3. https://bugzilla.redhat.com/show_bug.cgi?id=1364781 glibc 2.24 (2.23.90) breaks Chromium and QtWebEngine Received signal 4 ILL_ILLOPN 7f58262eac90 Apparent cause: glibc Reason: bisecting of OpenEmbedded changes by the OpenEmbedded folks: https://www.mail-archive.com/openembedded-core@xxxxxxxxxxxxxxxxxxxxxx/msg82915.html F25 affected?: probably yes (it has the same glibc version) Workaround: none known In addition to these issues, there are also 4 crashes in the Nouveau graphics driver that can make QtWebEngine and probably Chromium crash: 1. https://bugzilla.redhat.com/show_bug.cgi?id=1349608 (pushbuf_kref, invoked by nv50_flush) 2. https://bugzilla.redhat.com/show_bug.cgi?id=1350275 (nouveau_fence_trigger_work) 3. https://bugzilla.redhat.com/show_bug.cgi?id=1362307 (nouveau_pushbuf_data) 4. https://bugzilla.redhat.com/show_bug.cgi?id=1364756 (nv50_screen_fence_update) I reassigned them to xorg-x11-drv-nouveau, but they have still not been looked at by a Nouveau maintainer. Considering that these issues break both the only up-to-date Qt browser (QupZilla) and the high-profile Chromium browser, I think they should have a really high priority.
