Bug 292368

Application: scangui (1.9.0)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.4
Operating System: Linux 2.6.41.4-1.fc15.x86_64 x86_64
Distribution: "Fedora release 15 (Lovelock)"

-- Information about the crash:
Attempted to scan a document from my HP c309a printer/fax/scanner. I scanned using the setting 600dpi and linear exposure. The document scanned to about 70%. I was presented with a save file dialog box. I entered the name of the document and selected the path in which I wanted it saved. I pressed save. The application crashed.

-- Backtrace:
Application: Acquire images (scangui), signal: Segmentation fault
87	  int result = INLINE_SYSCALL (poll, 3, CHECK_N (fds, nfds), nfds, timeout);
