| Summary | 0002381: Crash after clicking to scroll | ||||||||
| Description | I saw this a couple of days ago on http://www.fanfiction.net but haven't bothered to report it - now it's happened again when scrolling down a Gmail window. Almost certainly the result of some recent change, as I've never experienced scrollbar-related issues on any site before. Netsurf occasionally crashes with a segfault when I click on the well of the scrollbar to scroll down. JavaScript was enabled at the time, and the log suggests that the crash is JS-related. | ||||||||
| Steps To Reproduce | Not reproduceable to order, unfortunately. | ||||||||
| Additional Information | Iyonix Aria, RISC OS 5.20 Snipped log (last thousand lines or so) attached. | ||||||||

I managed to get a segfault while trying to reproduce the symptoms (Iyonix, RO 5.22, CI#3049). Log_02 attached, which shows: fire_dom_event: Dispatching 'click' against 0x0 I couldn't see any scrollbars but the ordinary RISC OS ones, which seemed to work OK - Harriet, if there are any more details about how to get it to happen, please add them in a note. |

Got the way to recreate it on fanfiction.net. Drag the horizontal scroll bar all the way over to the right. A beige area appears between the main window content and the vertical scroll bar. Click in that area and you guarantee a segfault. The area of the same colour below the main content does not cause a segfault. Log_03 is another log of the same. |

It happens identically on the linux gtk version built from today's source. My guess is that an area that shouldn't be sensitive to clicks, has been given (or left with) sensitivity. Apart from fixing that problem - which you have to get right, every time, for every pixel of every page, no matter how the window size, scroll bars, etc. are dragged around - but you can also fix it by refusing to dispatch clicks agains null objects. Belt and braces suggests that both are desirable. |
