Hello everyone! Recently I've received two crash reports for Geeqie 1.1 (patched a bit) from somebody who had browsed through a collection of large TIFF files (>25 MB). The crash is not reproducible, but might be related to skipping to the next file while loading the current file is not done.
The symptoms are similar. While gdk-pixbuf mentions width = 7898 height = 3318 Geeqie's own code in pr_zoom_clamp at pixbuf-renderer.c:1755 refers to w = 0 h = 0 but the reason for the crash is it somehow uses an invalid pixbuf renderer, when trying to call pr->renderer->invalidate_all(pr->renderer), and segfaults. https://bugzilla.redhat.com/attachment.cgi?id=960178 The call of pr_zoom_clamp() leads back to pixbuf_renderer_set_size_early(), unless I misread the code. The second time the user has encountered a crash, it ran into a NULL pixbuf renderer pointer early in pixbuf_renderer_set_size_early(), #0 pixbuf_renderer_set_size_early (pr=0x0, width=3465, height=5202) at pixbuf-renderer.c:2916 zoom = 1 2915 zoom = pixbuf_renderer_zoom_get(pr); 2916 pr->image_width = width; 2917 pr->image_height = height; and interestingly, pixbuf_renderer_zoom_get(pr) tries to protect against an invalid "pr" ptr, g_return_val_if_fail(IS_PIXBUF_RENDERER(pr), 1.0); but that doesn't help outside that function, of course. https://bugzilla.redhat.com/attachment.cgi?id=962883 It looks like some sort of race to me. Any ideas, anyone? ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
