Thanks for the detailed report! This is a Qt bug, but in Qt 5.5 there were various fixes related to that (e.g. this). Can you install the |

[1] 858 abort (core dumped) python3 qutebrowser.pyI'm probably missing something trivial here, but I'd appreciate any hints :) |

The first issue is because you're running a release, but your config file has new stuff (from master) in it. For the second output, you'll have to install the other beta packages too by hand. It seems like I didn't correctly set the dependencies (it started as a quick experiment for myself). I currently can't check what packages you need to install exactly, but you can get a list of packages like this:
Then try to install them all - I think two will be missing (I didn't build them because there are no C extensions) - remove them, and you should be good to go. |

Huh. I guess running the repo version inserted new configuration into ~/.config/qutebrowser. I removed the unsupported entries and now I got the same errors for both. I did: and qutebrowser now runs as usual. I tried reproducing the issue by undocking/redocking, and alas, nothing coredumps! Thanks a bunch (and thanks for a browser that seems to be what I've been looking for for a few years, now). |

Glad to hear! If you want to keep the beta packages, just keep in mind to manually revert to the normal ones once Qt 5.5 is released (hopefully soon) - I'll post a message to the mailinglist when it's released. You're welcome! 😄 |
Docking/undocking my Thinkpad T430s leads to qutebrowser segfaulting and dumping core. I haven't yet found a way to narrow down the steps to reproduce, but I've extracted a stacktrace in accordance with the instructions at http://github.com/The-Compiler/blob/master/doc/stacktrace.asciidoc. I used the pre-built symbols.
I'm running Arch Linux.
