My eventual screen size was actually larger than what I specified as -geometry on the command line - it took up the entirety of my screen (1920x1200). Not sure if that matters.
This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component.
Are you still seeing this problem? It would help to see a more complete backtrace, which you can obtain by first running "debuginfo-install tigervnc-server".
Yes, the bug is still present in F18. It seems to be fixed upstream though - I can't reproduce the bug using TigerVNC trunk.
Installing the debuginfo packages didn't appear to improve the backtrace unfortunately.
This message is a reminder that Fedora 17 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 17. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '17'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 17's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 17 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora, you are encouraged change the
'version' to a later Fedora version prior to Fedora 17's end of life.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Should be fixed in tigervnc-1.3.0-1.fc19.
tigervnc-1.3.0-1.fc19 has been submitted as an update for Fedora 19.
tigervnc-1.3.0-3.fc19 has been submitted as an update for Fedora 19.
* should fix your issue,
* was pushed to the Fedora 19 testing repository,
* should be available at your local mirror within two days.
Update it with:
# su -c 'yum update --enablerepo=updates-testing tigervnc-1.3.0-3.fc19'
