The problem and a temporary solution (simply removing `'\\mathdefault'`) is fully described on [Stack Overflow](https://stackoverflow.com/questions/47253462/matplotlib-2-mathtext-glyph-errors-in-tick-labels/47850541#47850541).\r\n\r\n**Code for reproduction**\r\n```python\r\nimport matplotlib\r\nimport matplotlib.pyplot as plt\r\n\r\n# Customize matplotlib\r\nmatplotlib.rcParams.update({# Use mathtext, not LaTeX\r\n                            'text.usetex': False,\r\n                            # Use the Computer modern font\r\n                            'font.family': 'serif',\r\n                            'font.serif': 'cmr10',\r\n                            'mathtext.fontset': 'cm',\r\n                            # Use ASCII minus\r\n                            'axes.unicode_minus': False,\r\n                            })\r\n\r\n# Plot\r\nplt.semilogy([-0.03, 0.05], [0.3, 0.05])\r\nplt.savefig('test.png')\r\n```\r\n\r\n**Actual outcome**\r\n```\r\npython/lib/python3.6/site-packages/matplotlib/mathtext.py:866: MathTextWarning: Font 'default' does not have a glyph for '\\times' [U+d7]\r\n  MathTextWarning)\r\npython/lib/python3.6/site-packages/matplotlib/mathtext.py:867: MathTextWarning: Substituting with a dummy symbol.\r\n  warn(\"Substituting with a dummy symbol.\", MathTextWarning)\r\n```\r\n![Actual test.png](https://i.imgur.com/8djsVrm.png)\r\n\r\n\r\n**Expected outcome**\r\n![Expected test.png](https://i.imgur.com/Ywvp09Z.png)\r\nThis is only a problem with matplotlib 2.x, as 1.x never automatically places minor ticklabels. \r\n\r\n**Matplotlib version**\r\n  * Operating system: Linux\r\n  * Matplotlib version: 2.0.2, but the bug is consistently reproduced in all of matplotlib 2.x\r\n  * Matplotlib backend: Agg, TkAgg\r\n  * Python version: 3.6\r\n\r\nI have installed Python and matplotlib from source.","author":{"url":"https://github.com/jmd-dk","@type":"Person","name":"jmd-dk"},"datePublished":"2017-12-16T23:16:25.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":15},"url":"https://github.com/10029/matplotlib/issues/10029"}
