I don't know the exact the steps to reproduce this problem. But for me, most of the time, it is when I am in non-edit mode, mouse button clicked and trying to drag the pointer over the widget. Here is the backtrace: gtktiledviewer: /opt/libreoffice/sw/source/uibase/uno/unotxdoc.cxx:3222: virtual void SwXTextDocument::postMouseEvent(int, int, int, int): Assertion `false' failed.

argv=0x7fffffffda48) at /opt/libreoffice/libreofficekit/qa/gtktiledviewer/gtktiledviewer.cxx:485 This might not be a problem with the widget but rather in LO core as specified by above debug message : sw/source/uibase/uno/unotxdoc.cxx:3222: virtual void SwXTextDocument::postMouseEvent(int, int, int, int): Assertion `false' failed.
Could you be a bit more specific? What do you mean when you say "to drag the pointer over the widget"? Which widget?
This is I do : When in non-edit mode, I am hovering my mouse pointer on the widget (say going from left to right side of the widget), and then suddenly press the mouse button for few seconds while still going towards right side, it crashes for me.
I found another way to reproduce this bug which works in both edit and non-edit mode In short, you just have to do a double click with your second click's release not at the same position where you clicked your first click. Let me know if it works for you.
I still fail to reproduce this. Certainly someone else will reproduce this.
Hello Pranav, what's your version of LO and OS? I cannot reproduce under linux on master. Widget is toolbar or something else?
By widget, I mean the drawing area in gtktiledviewer. I am on Fedora 22, LO master. And, I might be unclear previously. This is when you run the gtktiledviewer, not the LO suite. G_MESSAGES_DEBUG=all bin/run gtktiledviewer $PWD/instdir/program file.odt
Hi Raal, I hope you were able to reproduce it this time (?).
It is also possible to reproduce this bug in "Notes" mode while editing .odp files.
I could reproduce it with the same trace. Miklos: noticing http://cgit.freedesktop.org/libreoffice/core/commit/?id=7297feb6bcc89c55d1768794754f3b7d796c4c75, thought you might be interested in this one. Was it on purpose to put assert(false) for default (and so for LOK_MOUSEEVENT_MOUSEMOVE)? If yes, how to avoid the crash?
Miklos: sorry, I put a comment for you in my previous comment, had just forgotten to put you in cc.
Yes, desktop-style "click to the start, then drag to the end" selections is not implemented for Impress in the LOK API. I'll take care of that.
