Description Lubomir Rintel 2014-02-20 10:07:52 UTC

Description of problem:

$subj

Version-Release number of selected component (if applicable):

gnome-calculator-3.8.2-1.el7.x86_64

How reproducible:

Always

Steps to Reproduce:
1. Switch to Binary
2. Type 10000
3. Press Enter
4. Switch to Decimal

Actual results:

(gnome-calculator:29882): Gtk-WARNING **: Invalid text buffer iterator: either the iterator is uninitialized, or the characters/pixbufs/widgets in the buffer have been modified since the iterator was created.
You must use marks, character numbers, or line numbers to preserve a position across buffer modifications.
You can apply tags and insert marks without invalidating your iterators,
but any mutation that affects 'indexable' buffer contents (contents that can be referred to by character offset)
will invalidate all outstanding iterators

(gnome-calculator:29882): Gtk-CRITICAL **: gtk_text_buffer_insert_with_tags: assertion `gtk_text_iter_get_buffer (iter) == buffer' failed

Expected results:

Additional info:

I've bisected the git history to find a fix. I've verified it to work: https://git.gnome.org/browse/gnome-calculator/commit/?id=11cf691

I'm glad upstream rewritten the calculator in Vala, but I've encountered some really scary bugs (and bitterly funny) in the Git log. I strongly suggest you take a look at it too and pick the most serious ones into RHEL. See for yourself: https://git.gnome.org/browse/gnome-calculator/commit/?id=917fafcb0

By the new calculator is ridiculously difficult to use. A drop down to select a numeric base? Seriously? Could it be a radio button box again? :/

Comment 2 Lubomir Rintel 2014-02-20 10:17:44 UTC

In all seriousness:

~♥ echo '1 + 2 - 3 * 4 / 5' |bc
1
~♥ echo '1 + 2 - 3 * 4 / 5' |gcalccmd
> 0.6

** (process:31108): CRITICAL **: string_strip: assertion `self != NULL' failed

Comment 3 Lubomir Rintel 2014-02-20 10:23:33 UTC

Oh, ignore me. It's just bc not using floats.

Comment 4 RHEL Program Management 2014-03-22 05:59:22 UTC

This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.

Comment 5 Laszlo Ersek 2014-03-31 09:03:33 UTC

Extremely annoying bug, please fix.

Comment 7 Vladimir Benes 2015-05-06 14:21:37 UTC

It's fixed in 3.14.

Comment 9 Martin Simon 2015-09-02 09:53:58 UTC

I've re-tested this bug in gnome-calculator-3.14.1-2.el7.x86_64. According to comment 7 and my results, I assume the bug is fixed. The conversions among number bases are working just fine.

The reproducer has been incorporated into our gnome-calculator test plan.
