Bug 876861 – mail-client/thunderbird-bin: opening links in firefox broken

• Product: Gentoo Linux
• Status: UNCONFIRMED ---

[Description Jonas Jelten 2022-10-12 14:23:08 UTC]

Thunderbird leaves LD_LIBRARY_PATH set when invoking firefox to open a clicked link. Firefox then crashes, because the thunderbird-bin libraries are preferred.

Hacky fix: patch /usr/bin/firefox to unset LD_LIBRARY_PATH.

It works fine for me... Opening a link from thunderbird-bin opens in firefox (non-bin) just fine.

I have firefox-105.0.2 and thunderbird-bin-102.3.2.

thunderbird's env contains: LD_LIBRARY_PATH=/opt/thunderbird

stracing thunderbird when clicking the notification link to this bugreport yields in some subprocess:

execve("/usr/libexec/gio-launch-desktop", ["/usr/libexec/gio-launch-desktop", "firefox", "https://bugs.gentoo.org/show_bug.cgi?id=876861"], 0x7f435f5d8400 /* 104 vars */) = 0
brk(NULL)                               = 0x555c2a54d000
mmap(NULL, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7f0763eee000
[...]
execve("/usr/lib64/firefox/firefox", ["/usr/lib64/firefox/firefox", "https://bugs.gentoo.org/show_bug.cgi?id=876861"], 0x5595d72266d0 /* 106 vars */) = 0
[... loads many libraries and tries LD_LIBRARY_PATH first]
openat(AT_FDCWD, "/opt/thunderbird/libc.so.6", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
openat(AT_FDCWD, "/usr/lib64/firefox/libc.so.6", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
openat(AT_FDCWD, "/lib64/libc.so.6", O_RDONLY|O_CLOEXEC) = 3
[...]
openat(AT_FDCWD, "/opt/thunderbird/libssl3.so", O_RDONLY|O_CLOEXEC) = 4
[... no other tries for libssl3.so, even though we should use /usr/lib64/libssl3.so from dev-libs/nss]
write(2, "XPCOMGlueLoad error for file /usr/lib64/firefox/libxul.so:\n/opt/thunderbird/libssl3.so: version `NSS_3.80' not found (required by /usr/lib64/firefox/libxul.so)\n", 160) = 160
[...]
write(2, "Couldn't load XPCOM.\n", 21)  = 21
[...]
exit(255)


so firefox is using thunderbird-bin's libssl3.so which is incompatible.

if I unset LD_LIBRARY_PATH in the firefox launch script, all is well.

Whether or not it's "safe" depends on your exact versions of both.
