Subject: kdevelop printing fails
From: ravi at ee.eng.ohio-state.edu

Package: kdevelop
Version: 2.0.1
Severity: grave
Installed from: Source

Hello,
  I installed kdevelop 1.4beta from sources. Everything seems to work fine except printing. When I attempt to print using enscript (with appropriate options), one of the following always happens:

1. KDevelop hangs with the following message repeated thrice on stderr:
    Double QObject deletion detected.
2. KDevelop returns to normal after the OK button is pressed and nothing is printed. Printing to file does not work either. There is no message on stderr.
3. KDevelop crashes with a SIGSEGV. The back trace generated by the KDE crash handler for this case is appended at the end of this message.

The choice of the 3 responses above seems to be dictated by my choice of options from the enscript options dialog. However, I have not been able to ascertain an exact causal relationship with particular options.

I checked the strings that should be passed to the command shell in CPrintDlg::slotOkClicked() and that seems to be ok. I can print with that string from the command line. However, for the responses 1 and 3, the code apparently never gets to the shell.

Any help appreciated,
Ravi
