Bug 230333

also crashes upon loading "about:plugins" in URL bar 

Created attachment 149006 [details]
strace.epiphany

tried to load the java test url while the strace was captured

gcjwebplugin or proprietary JVM?

> gcjwebplugin or proprietary JVM?

Its properitary JVM "j2re1.4.2_02" - please also note that after appying
epiphany extentions todya it at-least does not crashes on loading
"about:plugins" but still crashes on loading any Java VM applet. 

Regression from other updates, Martin?

Could be. I could not reproduce it on my box so I'll check it on a clear fc6.

It affects firefox, too.

Firefox works fine for me so far, I am using it as a stop gap arrangment till
Epiphany is fixed. 

Hmm, strange. But I can reproduce it, at least.

Can you please check the latest java? jre-1_5_0_11-linux-i586.rpm

Hmm, j2re1.4.2_02 crashes with previous packages, too:

firefox-1.5.0.9-2.fc6
epiphany-2.16.3-1.fc6

jre-1_5_0_11 works fine.

I tried with jre-1_5_0_11 as well, crashed again I need to get this working with
j2re-1.4.2_02-3 more important. However I installed epiphany-debuginfo package
but I had issues getting the BT. I am attaching the strace for now. 

firefox-1.5.0.10-1.fc6
epiphany-2.16.3-2.fc6
epiphany-debuginfo-2.16.3-2.fc6

$ strace -o /tmp/epiphany.3 -r -v -f -t -p5874

Through the day trying to understand this issue a new finding had been that
epiphany started crashing more often, even it crashed now while attaching the
previously mentioned attachment. But then Bug Buddy got excited and I got get a
little useless backtrace, I am attaching it here still and request for a bit of
guidence for what more I information I can help for this issue ?

It crashes somewhere in java plug-in. You can probe the next one, stored in 

/usr/java/j2re1.4.2_02/plugin/i386/ns610/libjavaplugin_oji.so

but it crashes for me, too.

The next problem could be missing /usr/lib/libXp.so.6, but it worked before the
update (right?) so I don't propose it...

No on this system, I am not missing libXp - libXp-1.0.0-8 

It crashes because the "navigator.userAgent" string in epiphany-2.16.3-2.fc6 is
too long (it looks like a limit is 128 chars). I hacked a bit the binaries and
it works fine for me now. I'll update CVS tomorrow.

Thats a great news, can you please share your workaround for now ?

I removed string "Epiphany/2.16" from epiphany binaries. Open /usr/bin/epiphany
in some hexa editor (e.g. hexedit), find "Epiphany/2.16" string and place 0x00
instead of the first letter ('E').

Yeah this is working like a charm ! and was the only salvage tonight when
firefox started crashing on me. Many thanks! 

firefox-1.5.0.10-5.fc6 epiphany-2.16.3-3.fc6 has been pushed for fc6, which should resolve this issue.  If these problems are still present in this version, then please make note of it in this bug report.
