Crash on startup: 'Cairo error "invalid value (typically too big) for the size of the input (surface, pattern, etc.)"''

Cairo-Dock Core

Bug Description

I just updated my Arch Linux install the other day, and after that (possibly related, possibly not) cairo-dock started crashing on startup with the following error message. It then tries to restart a few times and eventually launches itself into maintenance mode, where it shows me the configuration window, but the dock never shows up even if I close that window.

I'll try removing some of the applets and see what happens; I'll report back here if I can find out any more information.

  Cairo-Dock has crashed (sig 6).
It will be restarted now.
Feel free to report this bug on to help improving the dock!
info on the system :
Linux atlantis 4.16.7-1-ARCH #1 SMP PREEMPT Wed May 2 21:12:36 UTC 2018 x86_64 GNU/Linux
Couldn't guess if it was an applet's fault or not. It may have crashed inside the core or inside a thread
restarting with 'cairo-dock -w 2 -q 1'...

Steps to reproduce from an empty .config/cairo-dock:

1. Start `cairo-dock -o` and enter configuration.
2. Enable advanced mode.
3. Under Docks, make the following changes:
    - in Background, change Style to "Image"
    - in Views, change Main Dock to "3D plane".
4. Apply and close configuration.
5. Restart cairo-dock.

I get many of the same warnings on another up-to-date Arch Linux machine where cairo-dock works fine, so the relevant portion of the output above appears to be the part starting at "thread '<unnamed>' panicked".

Downgrading librsvg from 2:2.42.4-1 to 2:2.42.3-1 is a workaround for me on my Arch machine. Seems like Cairo-Dock needs to be update to support the new librsvg version.

Reported the problem upstream, not sure if anybody will read it there though, the forums looks dead but I couldn't find a better place for reporting a bug:

Jed Liu (jed-ubuntu-com) wrote :

Thanks for tracking down the librsvg issue, and for reporting it upstream. I'm not optimistic for a fix, though. It looks like Cairo-Dock has been abandoned. The last commit to core was in Sep 2016:

I've looked for alternatives and have settled on latte-dock, which seems to integrate well with Plasma. Plank looked nice too. Both are in the Arch community repos.

Well, I wouldn't give up on Cairo-Dock so fast, it has received no development during the last year, but already for several years there were only 2-3 commits per year were pushed done, so I assume that we can hope the development to continue with this slow pace rather than being completely dead. If the developers receive the bug report, I am quite positive that the issue will be fixed. I would propose to wait for some reaction to my post on the official forums and, if none follows for some days, contact the devs by mail.

Sent a mail three days ago, no reply yet - looks like I was wrong in the end...

Changed in cairo-dock-core:
status: New → Confirmed

Reported at Arch's bug tracker as well:

Further findings:

1. The bug appears on some machines but not on all: I have a Manjaro install where librsvg has been updated to .4 already and the bugs doesn't appear.

2. The bug appears only if the plugins package cairo-dock-plug-ins is installed.

3. Rebuilding the core and plugins packages didn't solve the issue.

4. The first commit to librsvg causing this bug is Bisection log:

Can anybody confirm any of these?

Reported issue upstream at librsvg:

The issue will be fixed in librsvg 2.42.5. Though the origin of the problem is in cairo-dock, librsvg will now handle the problem without crashing.

librsvg 2.42.5 has landed in Arch now.
