A user posted the following message: When running rssowl_linux_1_1_2005_03_12_bin, clicking anywhere, on any page, in the internal browser, causes rssowl to crash with an error like this: # # An unexpected error has been detected by HotSpot Virtual Machine: # # SIGSEGV (0xb) at pc=0x0829ade9, pid=24325, tid=16384 # # Java VM: Java HotSpot(TM) Client VM (1.5.0_01-b08 mixed mode, sharing) # Problematic frame: # C 0x0829ade9 # # An error report file with more information is saved as hs_err_pid24325.log # # If you would like to submit a bug report, please visit: # http://java.sun.com/webapps/bugreport/crash.jsp # ./run.sh: line 2: 24325 Aborted java -Xmx134217728 -jar -Djava.library.path=. rssowl.jar This is using mozilla-1.7.6-0.cvs.20050309 on Fedora Core 4 test 1. The external browser (same version of mozilla) does not exhibit this bug. Note that this RSSOwl version is using the latest SWT. Ben
Same problem occurs with the mozilla-1.7.3-xft-gtk2, mozilla 1.7-xft-gtk2 and mozilla 1.6-xft-gtk2 builds from mozilla.org - even though the FAQ implies that 1.6 should definitely work! This is with libswt-mozilla-gtk-3123.so.
Robin: can you try these GTK2 builds from the Mozilla XFT website http://www.braindrain.be/mozilla/ In particular: http://www.braindrain.be/mozilla/tar/mozilla-1.6-xft-gtk2-pc-linux.tar.bz2 Or this 1.7 build one: http://www.braindrain.be/mozilla/tar/mozilla-1.7-xft-gtk2-pc-linux-gnu.tar.bz2 We suspect there are intermittent crashes with the GTK2 builds contributed by Mozilla.org, but not with the ones from Mozilla XFT (bug 84053). Please let us know if these builds are 'fixing' the crashes for you. *** This bug has been marked as a duplicate of 84053 ***
The same bug occurs with _both_ of those. I believe this is a new issue.
We have not tested Fedora Core 4 test 1 yet. The Browser seemed to work fine in Red Hat EL4 (Mozilla 1.7.3 and Firefox 1.0).
The same bug occurs on Fedora Core 3, with RSSOwl 1.1 final, so it is not a Fedora-4-specific issue.
valgrind --tool=addrcheck shows the following errors after the user clicks, and after these errors the program segfaults: ==29483== Invalid read of size 4 ==29483== at 0x381C5F43: ???

From a user: This appears to be caused by a bug in the popup blocking code in rssowl.

He checked that this bug does not occur when popup blockling is disabled in RSSOwl. What I am doing if popup blocking is enabled is: Inside VisibilityWindowListener#show() I am disposing the Browser. Looking into the Snippet that shows popup blocking, this is done in an asyncExec. I am not doing it inside an asyncExec. May this be the problem? Ben

Ben, does this still happen for you?
I think not. Feel free to close. I can open new bugs if I get news from my linux users. Ben
Thanks
