Crash after selecting "Enable Continuous Logging" when no connection active

[mdear]

I invoke SavvyCAN on my Linux Mint device, see that no frames are coming in and no connections exist, select "Enable Continuous Logging" and the app crashes.

Do you, by chance, use Wayland instead of X11? I know various people have reported problems like this where it complains about Gtk related things and I thought it was due to the use of Wayland.

This looks like the same crash as reported in here: #725 #621 #414

The fix suggested by @TadayukiOkada fixes the issue. The steps are pretty straightforward:

# Open a terminal and cd to the directory containing the AppImage.
# Extract the AppImage:

./SavvyCan-x86_64.AppImage --appimage-extract
# (This creates a directory called squashfs-root)

# removing libpango from the AppImage fixes the problem:
rm ./squashfs-root/usr/lib/libpango-1.0.so.0*

# Download the AppImage creation tool and make it executable:
wget https://github.com/AppImage/AppImageKit/releases/download/continuous/appimagetool-x86_64.AppImage
chmod +x appimagetool-x86_64.AppImage

# Make a new AppImage using the updated directory:
./appimagetool-x86_64.AppImage squashfs-root

# This will create an updated AppImage named SavvyCan-x86_64.AppImage
