Crash on paste in text box

[Diederik van Lierop]

Inkscape crashes when pasting into a text box, i.e. while editing the text, but this is hard to reproduce. I've encountered this on two different documents.

ERROR:ui/clipboard.cpp:1084:void Inkscape::UI::ClipboardManagerImpl::_onGet(Gtk::SelectionData&, guint): assertion failed:(_clipboardSPDoc != NULL)

Program received signal SIGABRT, Aborted.
0x00000030a1e32f05 in raise () from /lib64/libc.so.6

We should at least get rid of this assertion! I'm on Fedora 11, using Inkscape build 22177. Here's a backtrace:

cannot reproduce on Windows build for 0.47pre2 rev 22153.
could you provide more details on steps to reproduce?

[jazzynico (jazzynico)]

Not reproduced on Ubuntu 9.04, Inkscape rev. 22183.
Did you copy from another application or from Inkscape?

[Diederik van Lierop (mail-diedenrezi)]

Three people helping out in triaging, ain't that great? What a lovely community we have! :-)

I copied from Inkscape to Inkscape, while editing text. So I pasted while the text cursor was blinking. I'm not sure what was on the clipboard, nor whether I tried pasting the style or tied basic pasting. I just tried again, but I haven't been able to reproduce this. Yesterday I succeeded in this, but only once.

When looking in the source code I found this comment below: I'm quite sure that I was pasting into Inkscape, but the crash occurred in code that handles pasting outside Inkscape. That's weird!

/**
 * @brief Callback called when some other application requests data from Inkscape
 *
 * Finds a suitable output extension to save the internal clipboard document,
 * then saves it to memory and sets the clipboard contents.
 */
void ClipboardManagerImpl::_onGet(Gtk::SelectionData &sel, guint /*info*/)
{
    g_assert( _clipboardSPDoc != NULL );

@thanks Diederik - finally a clue to what is happening in (possibly related but not-crashing) these bugs:
Bug #347987 in Inkscape: “Strange random error message”
Bug #381540 in Inkscape: “Paste randomly invokes PDF import”
Bug #418242 in Inkscape: “uniconvertor error message about font substitution problems”

and probably others...

[su_v (suv-lp)]

Maybe this tool is helpful to monitor the content type of the clipboard:
<http://sourceforge.net/projects/dragndrop/> by Jon A. Cruz.

He mentioned it recently on inkscape-user in a thread about a clipboard issue on OS X:
<http://thread.gmane.org/gmane.comp.graphics.inkscape.user/12631/focus=12636>

I could not get it to display the clipboard _content_ though (only 'dragndrop' content like swatch colors or some text/numbers from the controls toolbar.

I'm a reporter of two of the bugs cited by ~suv. In my case those errors are pretty random and hard to reproduce. It depends on what is being copied, and I can't reproduce the bug always, sometimes it happens, sometimes doesn't.
It may sound weird, but it also looks like it depends on the fonts installed in the system, or the programs running.

It's annoying and frustrating, since there isn't a way to reliably reproduce the error. But the error can be so frequent in a session that it can make it impossible to complete the work.

Acording my personal oppinion and experience, I think this bug is important enough to be marked as critical, and a showstopper for 0.47
Of course there are other important bugs, but this turns working with inkscape into a nightmare.

Bug #347987 in Inkscape: “Strange random error message”
Bug #418242 in Inkscape: “uniconvertor error message about font substitution problems”

I just found out that these errors appeared when I had a java program running (Free Rapid) . It took me some time to know it because I never thought that a so unrelated program could be triggering the error.
Anyway, the error is in inkscape, so there's something going on with the copy procedure, that in some way interferes with or is interfered by that Java program.
When I kill Java, inkscape goes back to the normal behavior, without errors during copying and paste.
My first guess was the clipboard monitoring function of that Java program, but the errors appear even after I de-activated that function.

Could you please check this? Is your system running some java software when you get this crash?
Is that copy routine found by Diederik related to my problems with that java program?

[Guillermo Espertino (Gez) (gespertino-gmail)]

I did some cleanup and unified the previous reports in a single one.
Bug #418242 and its duplicates are probably consequences of the same behavior reported in comment #3.

[su_v (suv-lp)]

possibly duplicates of this report:
Bug #496793 in Inkscape: “ctrl c ctrl v of text in edit mode crashes inkscape”
Bug #549219 in inkscape (Ubuntu): “crashes on copy/past in text mode”

both report the same error message:

Windows XP: Inkscape 0.48pre1 r9509
**
ERROR:src/ui/clipboard.cpp:1171:void Inkscape::UI::ClipboardManagerImpl::_onGet(Gtk::SelectionData&, guint): assertion failed: (_clipboardSPDoc != NULL)

**
ERROR:ui/clipboard.cpp:1086:void Inkscape::UI::ClipboardManagerImpl::_onGet(Gtk::SelectionData&, guint): assertion failed: (_clipboardSPDoc != NULL)

[Diederik van Lierop (mail-diedenrezi)]

Changing the status from incomplete to confirmed. We even know exactly where inkscape crashes and have stack traces.

[Alex Valavanis (valavanisalex)]

I think this is a duplicate of bug #496793. Both have the same backtrace, both are caused by copy/paste in text boxes and both are unrelated to java clipboard monitoring.

Please feel free to revert the duplicate status if you believe I am mistaken.
