Clicking a button in Java applet causes Firefox crash
Last modified: 2009-06-02 10:31:23 EDT
Description of problem:
Firefox crashes reproducibly when I click on a button in a particular applet.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Go to URL above
2. Click on "click to interact". This will start the applet.
3. Applet will display an error message, and a button to report the error back to the website. Click the button.
This is in VirtualBox 2.1.0 OSE on Mac OS X. I am unable to use GDB to debug firefox due to an issue with VirtualBox, which I am about to report.
Thanks for the bug report. We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue.
First of all, could we get output of the command
rpm -qa *xulrun* *firefox* *mozilla* *flash* *plugin*
Please also install firefox-debuginfo (debuginfo-install is from
Then run firefox with a parameter -g. That will start firefox running inside of gdb debugger. Then use command run and do whatever you did to make firefox crash. When it happens, you should go back to the gdb and run
(gdb) thread apply all backtrace
This produces usually many screens of the text. Copy all of them into a text editor and attach the file to the bug as an uncompressed attachment.
We will review this issue again once you've had a chance to attach this information.
Thanks in advance.
Created attachment 330900 [details]
session captured with script -c 'firefox -g' command
I used the command
script -c 'firefox -g'
instead of just firefox -g, to capture the backtrace, so I also got the Java backtrace(s) included in the attachment as well.
This not a Firefox bug -- java plugin crashed and took firefox with itself.
Reassigning to java components.
The problem was with the plugin. The applet made a showDocument() call with a url that had a newline, and that caused parsing problems and crashed the plugin. I have fixed it upstream. I'll close this bug when it gets into Fedora.
