 Posted: Wed Nov 18, 2020 6:57 pm Post subject: [SOLVED] Firefox Assertion failure: !locale.IsEmpty() |
 |
|
Hi,
I've recently updated @world and I am no longer able to run firefox when emerging www-client/firefox.
The ebuild runs without any problems, but when launching /usr/bin/firefox it crashes with Segmentation Fault.
I've enabled the debug USE-flag, which gives some more info:
| Code: |
$ firefox

I've found the line of code that is mentioned in the stack trace:
| Code: |
364 NS_IMETHODIMP
365 LocaleService::GetDefaultLocale(nsACString& aRetVal) {
366 // We don't allow this to change during a session (it's set at build/package
367 // time), so we cache the result the first time we're called.
368 if (mDefaultLocale.IsEmpty()) {
369 nsAutoCString locale;
370 // Try to get the package locale from update.locale in omnijar. If the
371 // update.locale file is not found, item.len will remain 0 and we'll
372 // just use our hard-coded default below.
373 GetGREFileContents("update.locale", &locale);
374 locale.Trim(" \t\n\r");
375 // This should never be empty.
376 MOZ_ASSERT(!locale.IsEmpty());
377 if (CanonicalizeLanguageId(locale)) {
378 mDefaultLocale.Assign(locale);
379 }
380
381 // Hard-coded fallback to allow us to survive even if update.locale was
382 // missing/broken in some way.
383 if (mDefaultLocale.IsEmpty()) {
384 GetLastFallbackLocale(mDefaultLocale);
385 }
386 }
387
388 aRetVal = mDefaultLocale;
389 return NS_OK;
390 }

and I've found this docu from Mozilla:
https://firefox-source-docs.mozilla.org/intl/locale_startup.html
https://firefox-source-docs.mozilla.org/intl/locale.html
But since I'm neither familiar with using gdb nor any Firefox internals, I'm a bit at a loss.
Can anyone point me into a direction how to find the root cause of this issue or how to fix it?
Things that I've tried:
- Enabling/disabling clang USE-flag
- Enabling/disabling l10n_en-GB USE-flag
- Enabling/disabling system-* USE-flags
- Emerging Firefox ESR version
- Playing around with LANG environment variable

FF83 works fine in my T9400 box.
If ESR get the same error,the problem most likely outside FF.
A broken RAM can trigger Segmentation Fault too. |

Thanks for the input.
I found out, that Firefox stores multiple files in /usr/lib64/firefox/omni.ja. It tries to load update.locale from there just before the assertion fails. For some unknown reason, the update.locale doesn't exist.
https://developer.mozilla.org/en-US/docs/Mozilla/About_omni.ja_%28formerly_omni.jar%29
If I manually add it, the assertion passes, but then Firefox crashes instead with

My firefox builds via emerge are working again! It seems, that I had to enable the dbus USE-flag...  |
