Bug 235183

Application that crashed: dolphin
Version of the application: 1.3
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-20-server x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
Twice, I had Dolphin open displaying an empty folder. From Firefox, I saved a complete web page, which saves an HTML file and a similarly named folder, to the folder being displayed by Dolphin. Both times, Dolphin crashed almost immediately.

I hypothesize that the creation of the file and the folder at virtually the same time caused the next directory scan by Dolphin to pick up more changes than it expected between scans, and it did not allocate enough memory to handle both changes at once. But without looking at the code, I really have absolutely no basis for this hypothesis.

To reproduce:
 1. Open an empty directory in Dolphin and let it sit there, displaying it
 2. Browse to a web page containing at least one image with Firefox (I'm running 3.5.9, if that makes any difference)
 3. Save the page to the directory open in Dolphin, with the type set to "Web Page, complete" (I saved it with a name ending in .html, but two different names besides for that)
 4. Dolphin will likely crash just after picking up the two new objects in the directory
