Description of problem: Crash occurs on this system simply by opening Applications (from Activities). An assertion can be seen in /var/log/messages, presumably from librsvg: "assertion failed: x < self.width as u32" 4-core Blackbird without GPU, F30 current.

I see (similar) crashes in librsvg2 with xfce4-panel (can be easily reproduced) and in xfce4-notifyd. Workaround is to downgrade to the previous librsvg2-2.45.90-1.fc30

librsvg2-2.46.0-2.fc30 is built with rust-1.37.0-1.fc30.ppc64le librsvg2-2.45.90-1.fc30 is built with rust-1.36.0-1.fc30.ppc64le
Is the problem perhaps higher up? You had that weird Gtk warning saying the content width was already -1.
I did a bit more testing with following results - librsvg2-2.45.90-1.fc30.dh.1.ppc64le rebuilt with rust 1.37 -> crash - librsvg2-2.46.0-2.fc30.dh.1.ppc64le rebuilt with rust 1.38 -> crash - librsvg2-2.46.0-2.fc30.dh.2.ppc64le rebuilt with rust 1.36 -> OK so I'm starting to suspect rust. Either it's more strict (but for ppc64le only, I'm not aware of any other report like this) or 1.37 introduced a bug.
Switching to rust for the maintainer to at least comment the issue.
Can you try with Rust 1.38 on Fedora 31 or rawhide? There we have LLVM 9, in case this is a new codegen issue.
It could be a codegen issue with LLVM8 at the end. Because when I rebuilt librsvg2 in F-31 buildroot with updates-testing enabled (rust 1.38 + llvm-libs 9.0.0 get installed), installed resulting librsvg2 rpm in a F-30 system, it works as expected, no crash.
OK, I'm moving this to LLVM, but I'll also try to further investigate the difference.
Let me know, if you would like to have access to a VM, where the issue can be reproduced.
Josh, can you come-up with an LLVM-only reproducer, based on rust-generated bitcode?
I don't know enough about what's actually going wrong to try to reduce it yet. The failed assertion makes sense given the Gtk-WARNING before it, so we'll have to track down what led to that unexpected state. Dan, does that Gtk-WARNING appear with the good librsvg2 builds too?
Josh, yes, the "Negative content width -1" warning appears also when the good librsvg2 is installed.
for the record - a workaround is to update to F-31 librsvg2 rpms in F-30
This message is a reminder that Fedora 30 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora 30 on 2020-05-26. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '30'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 30 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 30 changed to end-of-life (EOL) status on 2020-05-26. Fedora 30 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
