** Description changed:
+ SRU Info:
+ =========
+ [Impact]
+ Currently, libgrip causes a segfault crash when multiple instances of eog are
opened in quick succession. This does not occur under typical use cases, but
there may be instances where a user might select multiple images and open them
all at once. Or maybe a user double clicks on an image and opens it twice
accidentally.
+
+ [Development Fix]
+ The change, found in the upstream merge request associated with the bug,
ensures that only currently mapped top-level widgets are registered for
gestures. Currently, when any top-level widget is mapped all pending gesture
subscriptions are registered, and if one of them wasn't mapped yet libgrip
crashes. Note that this fix has not been uploaded in P because the P archive is
not open yet.
+
+ [Stable Fix]
+ Please see lp:libgrip/oneiric. The patch added to fix this issue can be found
at
http://bazaar.launchpad.net/~utouch-packaging/libgrip/oneiric/view/head:/debian/patches/0002-window_mapped_cb.patch.
+
+ [Test Case]
+ run gdb eog in a window
+ in another window cd to a directory with images in subdirectories and run the
following command:
+
+ while true; do eog "$(find . -type d|sort -R |head -1|cut -f 1)"; done
+
+ It opens a random subdir every iteration but crashes quite quickly. You
+ can try adding a little sleep:
+
+ while true; do eog "$(find . -type d|sort -R |head -1|cut -f 1)"; sleep
+ 1; done
+
+ [Regression Potential]
+ Medium. This change affects how libgrip registers for gesture events. There
is the potential that gestures will no longer be subscribed correctly. However,
gestures is a "value-add" feature. The loss of gestures will not affect the
fundamental functionality of the software.
