Description Robert Puskajler 2003-12-20 21:51:42 UTC
Version:           Quanta 3.2-Beta2 [Using KDE 3.1.94 (3.2 Beta 2)] (using KDE KDE 3.1.94)
Installed from:    Slackware Packages
OS:          Linux

Start Quanta, load project, start Cervisia plugin ...
The Quanta crashes when Advanced->Tag/Branch... is clicked.
On my system (slackware) the crash is 100% reproducable.
There are no other problems in Cervisia plugin.

The cervisia as a standalone application works well and does the tagging as expected.

Does it crash if you run Cervisia alone, or Cervisia inside Konqueror?

The Cervisia alone as a standalone application (CVS frontend) doesn't crash,
it opens the Tag dialog and works well ...

It will crash only when I run Cervisia plugin inside Quanta
and only when "Tag/Branch" operation (dialog) is requested.
All other Quanta and Cervisia plugin operations, I'm using, are working well.

To reproduce the crash follow the steps:
	- start Quanta [3.2-Beta2], load any project
	- click on "CVS Management (Cervisia)" icon
		or "Plugins" menu "CVS Management (Cervisia)" item
	- click on "Advanced" menu item "Tag/Branch ..."
	- Quanta crashes instantly

The cervisia plugin is configured:
	Name: "CVS Management (Cervisia)"
	FileName:  "kde3/libcervisiapart.la"
	Output Window: "Editor window"
	Input: "Project Folder"
	Location: (empty)
	Read Only Part: YES
	Validate Plugin: YES
[ which is the defualt configuration of Quanta ]

Here are the plugin files:

-rwxr-xr-x    1 root     root       692300 Dec  3 18:59 /opt/kde/lib/kde3/libcervisiapart.so

Subject: Re: crash in cervisia plugin when tagging/branching

Although it's only reproducable in Quanta, I still suspect that it's a 
Cervisia bug. I will update my Cervisia and provide a detailed BT for the 
Cervisia authors.

Comment 4 András Manţia 2004-01-13 11:29:45 UTC
For me it seems to be a Cervisia (or KPart? problem). Backtrace and valgrind log attached.

Comment 5 Christian Loose 2004-01-13 16:02:13 UTC
This is strange. I took a quick look at this (not at home right now) and the last bt line (taglib.cpp:39) is the following:

setCaption( (action==Delete)? i18n("CVS Delete Tag") : i18n("CVS Tag") );

since action is equal to Create it should do a simple:

setCaption( i18n("CVS Tag") );

Don't know how this can crash.

Can you reproduce this with language set to en_US?

Comment 6 Christian Loose 2004-01-14 09:45:10 UTC
I could reproduce it and I'm working on it.
