The line that seems to be triggering it below seems to be:
#0 0x00007f0e938e7262 in sqfs_init () from /usr/lib/libsquashfuse.so.0

But, for context, I was trying to run the Cemu appimage and Dr.Konqi basically had a seizure with an endless amount of crash pop-ups that wouldn't stop until I removed the associated packages.

In case it's relevant (I don't know if it is but I do know this never used to be an issue) I'll drop the compile options I used for AppImage Launcher:

The line that seems to be triggering it below seems to be: `#0 0x00007f0e938e7262 in sqfs_init () from /usr/lib/libsquashfuse.so.0` But, for context, I was trying to run the [Cemu appimage](https://github.com/cemu-project/Cemu/releases/tag/v2.0-45) and Dr.Konqi basically had a seizure with an endless amount of crash pop-ups that wouldn't stop until I removed the associated packages. In case it's relevant (I don't know if it is but I do know this never used to be an issue) I'll drop the compile options I used for AppImage Launcher: ```bash CC=clang CXX=clang++ AR="/usr/bin/llvm-ar" NM="/usr/bin/llvm-nm" AS="/usr/bin/llvm-as" RANLIB="/usr/bin/llvm-ranlib" OBJCOPY="/usr/bin/llvm-objcopy" export CFLAGS="-O3 -pipe -fno-plt -fpic -fpie -pthread -Wl,-z,relro,-z,now -w \ -fexceptions -minline-all-stringops -ftree-vectorize \ -Wp,-D_FORTIFY_SOURCE=2 -Wformat -Werror=format-security \ -fstack-clash-protection -fstack-protector-strong -fcf-protection \ -march=znver2 -mtune=znver2" CXXFLAGS="${CFLAGS} -Wp,-D_GLIBCXX_ASSERTIONS" LDFLAGS="-lc++abi -fuse-ld=lld -unwind=libunwind -lpthread -pie -Wl,-O3,--sort-common,--as-needed,-z,relro,-z,now" export DEBUG_CFLAGS="-g" export DEBUG_CXXFLAGS="${DEBUG_CFLAGS}" ``` <details><summary>appimagelauncherd backtrace:</summary> ```cpp PID: 5223 (appimagelaunche) UID: 1000 (neko-san) GID: 1000 (neko-san) Signal: 11 (SEGV) Timestamp: Fri 2023-07-28 16:27:22 CDT (7s ago) Command Line: /usr/bin/appimagelauncherd Executable: /usr/bin/appimagelauncherd Control Group: /user.slice/user-1000.slice/user@1000.service/app.slice/appimagelauncherd.service Unit: user@1000.service User Unit: appimagelauncherd.service Slice: user-1000.slice Owner UID: 1000 (neko-san) Boot ID: b40a6780fec74fcdbca80ac54d719559 Machine ID: abd5520acfca4eab87991ab6eaf70bb5 Hostname: ARCH Storage: /var/lib/systemd/coredump/core.appimagelaunche.1000.b40a6780fec74fcdbca80ac54d719559.5223.1690579642000000.zst (present) Size on Disk: 781.4K Message: Process 5223 (appimagelaunche) of user 1000 dumped core.
